- make _rl_digit_p succeed only for ascii digits, since that's what
most callers assume

+doc/bashref.texi
+ - added `ERR' trap and [-+]O invocation option to section listing
+ differences from the Bourne shell
+
+ 11/15

+[bash-2.05a released]
+
+ 11/19
+ -----
+include/stdc.h
+ - new define, INLINE, defined as `inline' for gcc and empty otherwise
+
+subst.c

+ - added rules to create PDF files from postscript and dvi input
+
+MANIFEST.doc
+ - added {article,bash,bashref,rose94}.pdf
+
+doc/bash.1
+ - rearranged some `.PD 0' and `.TP' directives so man2html will
+ handle them better (shouldn't affect groff output)
+
+support/man2html.c
+ - small fix to handle quoted string arguments to directives like
+ `.BR' without mangling the output
+
+ 11/20
+ -----
+{arrayfunc,variables}.c
+ - changed calling sequence for dynamic array variable `assign'
+ functions to (SHELL_VAR *self, char *value, arrayind_t ind)
+ - changed calling sequence for dynamic variable assign functions
+ to the same as array variable assign_func. Now this can be
+ prototyped
+
+variables.h
+ - the assign_func member of a `struct variable' is now of type
+ `sh_var_assign_func_t', which is prototyped
+ - the dynamic_value member of a `struct variable' is now of type
+ `sh_var_value_func_t', which is prototyped
+
+variables.c
+ - changed to use `sh_var_assign_func_t' and `sh_var_value_func_t'
+
+builtins/cd.def
+ - when in posix mode, if the new directory name formed by PWD and
+ the argument passed by the user cannot be canonicalized, and the
+ -P option has not been supplied, return failure immediately
+ - if canonicalization failed, but the fallback to the directory
+ name specified by the user succeeds, reset the current working
+ directory
+
+lib/readline/{input.c,rlprivate.h}
+ - renamed rl_unget_char to _rl_unget_char; made library global
+
+lib/readline/{{bind,readline}.c,{keymaps,rlprivate}.h}
+ - support for `key subsequences'; allows a key sequence and a function
+ mapped to a subsequence of that key sequence. Primarily to allow
+ arrow keys to be bound in readline vi insert mode, while preserving
+ the ESC function to switch to command mode.
+
+lib/readline/{input.c,rlprivate.h}
+ - new function, _rl_input_queued(T), does a check with select or
+ FIONREAD with a timeout of `T' (which is generally 0)
+
+lib/readline/readline.c
+ - change _rl_dispatch_subseq to test for input in the queue if we
+ get ESC while in vi insertion mode if the keymap entry type for
+ ESC is ISKMAP. If _rl_input_queued returns non-zero, we assume
+ that an arrow key sequence has been pressed and go ahead with the
+ subsequence. If it returns zero, we assume that the user pressed
+ ESC to switch into command mode, and dispatch to that right away.
+ This avoids forcing the user to press another key before switching
+ into command mode
+
+ 11/21
+ -----
+lib/readline/readline.c
+ - bind common arrow key sequences in vi insertion keymap
+
+lib/readline/terminal.c
+ - bind termcap definition's arrow keys in vi insertion keymap
+
+lib/readline/bind.c
+ - check for rl_vi_movement_mode in _rl_bind_if_unbound, so
+ binding the arrow keys can work
+
+lib/readline/readline.c
+ - since _rl_bind_if_unbound does the check of what's currently
+ bound to the key sequence, the check in bind_arrow_keys_internal
+ was redundant
+ - bind_arrow_keys_internal now takes a Keymap argument and handles
+ saving and restoring _rl_keymap; changed bind_arrow_keys
+ accordingly
+
+builtins/fc.def
+ - fix from Paul Eggert to substitute the nearest history number in
+ range if an out-of-range value is supplied. POSIX requires this
+
+lib/sh/pathcanon.c
+ - fix from Corrina Vinschen for the special `cygdrive' prefix on
+ Cygwin
+
+bashhist.c
+ - split the history adding code into more pieces:
+ check_history_control (char *line) checks LINE against the value
+ of HISTCONTROL, returning 1 if LINE should be saved and 0 if not
+
+ check_add_history (char *line) calls check_history_control and
+ history_should_ignore (line) and saves the line with
+ bash_add_history if the checks indicate that it should be saved
+
+ maybe_add_history just calls check_add_history to set the value
+ of first_line_saved
+
+bashhist.h
+ - extern declaration for check_add_history()
+
+shell.c
+ - don't call load_history() from the interactive shell startup
+ code if history_lines_this_session is > 0, indicating that we've
+ already saved some lines in the history and that we probably
+ don't want to overwrite them
+
+builtins/history.def
+ - call check_add_history from push_history, so `history -s xx'
+ works even when in a compound command whose first line has not
+ been saved. (Caveat: in a compound command when the first
+ line has been saved, the line supplied to history -s will become
+ part of the compound command's history entry. Of course, the
+ delete_history call could remove the compound command from the
+ history entirely)
+
+bashline.c
+ - use sh_makepath instead of xmalloc/sprintf in
+ command_word_completion_function
+
+lib/readline/complete.c
+ - get_y_or_n now takes an int FOR_PAGER argument; caller changed
+ If FOR_PAGER is non-zero, get_y_or_n returns appropriate values
+ for a more-like pager: `newline' or `return' return 2; `q' or
+ `Q' return 0
+ - there is now a mini internal more-like pager for displaying a
+ list of completions that exceeds the screen height (new function
+ _rl_internal_pager, called from rl_display_match_list)
+
+ 11/24
+ -----
+command.h
+ - new flag, W_TILDEEXP, says to do tilde expansion on an
+ assignment word
+
+execute_cmd.c
+ - fix_assignment_words now sets W_TILDEEXP for assignment word
+ arguments to `assignment builtins'
+
+general.c
+ - bash_tilde_expand now takes a second argument indicating whether
+ or not it's being invoked in an `assignment context'
+
+general.h
+ - change extern declaration for bash_tilde_expand
+
+{bashline,execute_cmd,findcmd,general,variables}.c
+builtins/evalfile.c
+lib/sh/makepath.c
+ - fix callers of bash_tilde_expand appropriately
+
+subst.c
+ - fix callers of bash_tilde_expansion appropriately
+ - add (currently commented-out) code that would tilde expand assignment
+ statement arguments to assignment builtins (W_TILDEEXP flag set)
+ even when the shell is in posix mode
+
+bashline.c
+ - fix attempt_shell_completion to turn off
+ rl_filename_completion_desired when doing command name completion,
+ so no slash gets appended to the name if there happens to be a
+ directory with the same name in the current directory
+
+ 11/26
+ -----
+lib/readline/rltech.texinfo
+ - a couple of additions to the rl_stuff_char description
+
+parse.y
+ - turn off echo_input_at_read in parse_string_to_word_list, so `set -v'
+ doesn't give extra lines of output when doing compound array
+ assignment
+
+subst.c
+ - fix split_at_delims to handle skipping over a `\n' if it's a
+ delimiter (use spctabnl(c) instead of whitespace(c))
+
+ 11/27
+ -----
+support/config.{guess,sub}
+ - updated (with bash changes) to latest version from gnu.org
+
+sig.h
+ - add prototype for set_signal_handler declaration
+
+builtins/setattr.def
+ - add prototype to extern declaration of declare_builtin
+

+ - add no_options call, since times takes no options
+
+lib/sh/spell.c
+ - add prototypes to forward declarations for midist and spdist
+
+lib/sh/strtrans.c
+ - add explicit int return type to ansic_shouldquote declaration
+
+lib/readline/rldefs.h, lib/readline/{macro,readline,util,undo}.c
+ - move define for SWAP to rldefs.h, removed from various C files
+
+lib/readline/vi_mode.c
+ - removed define for exchange(), changed to use SWAP instead
+
+lib/readline/bind.c
+ - added some static forward function declarations
+ - find_boolean_var, find_string_var now take a `const char *' argument
+
+lib/readline/signals.c
+ - added static forward declaration for rl_maybe_set_sighandler
+
+lib/readline/readline.c
+ - add some common key bindings for the HOME and END keys in
+ bind_arrow_keys_internal
+
+lib/readline/terminal.c
+ - fetch the `@7' termcap string; it's sent by the END key
+ - attempt to bind the terminal's END key to rl_end_of_line in
+ bind_termcap_arrow_keys; I don't know why I was using `kH'
+ instead of `@7'
+
+doc/builtins.1
+ - remove `case', `for', `if', `until', `while' from NAME section;
+ those are not shell builtins
+
+ 11/28
+ -----
+stringlib.c
+ - new function, find_token_in_alist, takes a token value and an
+ ALIST argument, and returns the string correspoinding to the
+ token if found in the alist
+
+externs.h
+ - new extern declaration for find_token_in_alist()
+
+subst.c
+ - string_list_internal is no longer static
+
+subst.h
+ - new extern declaration for string_list_internal()
+
+parse.y
+ - new alist array of other tokens returned by read_token which are
+ not reserved words in word_token_alist[]
+ - reworked error reporting: new functions print_offending_line,
+ which prints the line containing the syntax error,
+ error_token_from_token, which takes the current token and tries to
+ figure out its textual representation, and error_token_from_text,
+ which does the old job of finding the bad token by analyzing the
+ text of shell_input_line at the current index
+ - report_syntax_error now tries to figure out the token that caused
+ the syntax error by first looking at current_token and falling
+ back to the old method of textual analysis if that fails
+ - report_syntax_error doesn't say the token resulting from the textual
+ analysis of the input line is an `unexpected token'; it just
+ says there is a `syntax error near xxx'
+ - changed conditional command error reporting to use the value
+ returned by error_token_from_token if it's not null instead of
+ just using the token value in the message, since current_token
+ ends up being set to -1, and the text of the message from
+ report_syntax_error might not be exactly right
+ - change parse_string_to_word_list to set current_token to the
+ offending token returned by read_token before calling yyerror()
+ to make the error reporting do the right thing
+
+aclocal.m4
+ - fixed typo in BASH_CHECK_LIB_TERMCAP
+
+configure.in
+ - add check for isinf(3); define HAVE_ISINF_IN_LIBC if found
+
+config.h.in
+ - add define for HAVE_ISINF_IN_LIBC
+
+lib/sh/snprintf.c
+ - check for Inf and NaN, using isinf and isnan if they're found in

+ - use the current locale for thousands separator and decimal point
+ - recognize "'" flag; not implemented yet
+ - fix for snprintf/vsnprintf with length of 0 and string argument of
+ 0 with non-zero length
+
+builtins/read.def
+ - TMOUT is now the default timeout for `read' (and select) if set,
+ like ksh93 when reading from the terminal
+ - edit_line (called by read -e) now just does readline's filename
+ completion by setting rl_attempted_completion_function to NULL,
+ since e.g., doing command completion for the first word on the
+ line wasn't really useful
+
+execute_cmd.c
+ - changed select_command to return failure status if select_query
+ returns NULL, indicating that read_builtin returned
+ EXECUTION_FAILURE
+
+doc/{bash.1,bashref.texi}
+ - documented new TMOUT behavior
+ - slight change to the description of the test `-ef' option
+
+doc/bashref.texi
+ - added item to posix mode section describing failure behavior of
+ cd when invoked in logical mode and the pathname formed by
+ combining $PWD and the directory argument does not refer to an
+ existing directory
+
+ 11/29
+ -----
+execute_cmd.c
+ - fix execute_function to call dispose_function_env after

+ bash bug #117673)
+
+lib/readline/readline.c
+ - rl_forward -> rl_forward_char; rl_forward function for compatibility

+
+aclocal.m4
+ - new function, BASH_CHECK_MULTIBYTE, encapsulates checks for

+
+config.h.in
+ - add necessary defines for multibyte include files and functions

+ - add call to BASH_CHECK_MULTIBYTE
+

+ - add code to define HANDLE_MULTIBYTE if prerequisites are met
+

+
+bashhist.c
+ - first_line_saved -> current_command_first_line_saved; variable is
+ now global
+
+bashhist.h
+ - extern declaration for current_command_first_line_saved
+
+ 11/30
+ -----
+bashhist.c
+ - break the code that actually calls add_history out of
+ bash_add_history into a new function, really_add_history;
+ bash_add_history now calls really_add_history
+ - check_add_history takes a second `force' argument telling it
+ whether to call bash_add_history (force == 0) or really_add_history
+ (force != 0)
+
+builtins/history.def
+ - in push_history, call delete_last_history if the current command
+ has more than one line, the first line was saved, and
+ command-oriented history is active. This takes care of deleting
+ the right history element if `history -s' is used within a
+ compound or multiline command
+ - in push_history, call check_add_history with second argument of 1
+ to skip check of current_command_line_count and add the arguments
+ to history -s as a single separate history entry
+
+ 12/3

+lib/readline/complete.c
+ - append a slash to completed names which are symlinks to directories

+
+lib/readline/rlprivate.h
+ - extern declaration for _rl_complete_mark_symlink_dirs

+
+doc/bash.1, lib/readline/doc/{readline.3,rluser.texinfo}
+ - documented new `mark-symlinked-directories' variable
+
+ 12/4
+ ----
+variables.[ch]
+ - set_pipestatus_array now takes a second argument with the number
+ of processes in the array
+ - changed set_pipestatus_array to just modify the value in place if
+ the existing array has one element and the new array has one
+ element, and to modify existing values in place if new array has
+ more elements than existing array
+
+variables.c, jobs.c
+ - changed set_pipestatus_array callers
+
+jobs.c
+ - moved call to setjstatus() from set_job_status_and_cleanup to
+ wait_for, since set_job_status_and_cleanup is part of the SIGCHLD
+ signal handler call path, and race conditions accessing the
+ PIPESTATUS array will result for things like

+
+configure.in

+ - fix wraparound search problem in find_entry when searching for a
+ free entry when the table is full
+
+ 12/6
+ ----
+lib/malloc/table.c
+ - keep an `overflow bucket' around to use when the table is full,

+ - new static variable to keep a count of the number of MT_ALLOC
+ entries in the mem_table
+
+lib/sh/{oslib,clktck}.c
+ - if HAVE_LIMITS_H is defined, include <limits.h>

+
+builtins/ulimit.def
+ - changed getmaxuprc() to just call getmaxchild() and massage the
+ return value appropriately
+
+{jobs,nojobs}.c
+ - use the value returned by getmaxchild() in
+ mark_dead_jobs_as_notified instead of static CHILD_MAX
+
+jobs.c
+ - new function, compact_jobs_list, removes some number of jobs from
+ the jobs table and reallocates the table, copying the jobs that
+ are left from the old table to the new. Compaction happens from
+ the beginning of the list and removes dead jobs, and we make sure
+ to keep the last CHILD_MAX jobs as POSIX.2 requires
+ - call compact_jobs_list from stop_pipeline if we're in a subshell,
+ there are no free jobs in the jobs table, and the jobs table is
+ at or above some maximum limit
+
+execute_cmd.c
+ - change eval_arith_for_expr to set this_command_name to `((' before
+ calling evalexp, since it might be changed by evaluating the
+ loop body between evalexp calls
+
+trap.c
+ - change reset_signal to turn off the SIG_TRAPPED flag for the
+ given signal, so shell builtins and functions running in command
+ substitutions don't run the signal handlers (traps are not supposed
+ to be inherited by command substitutions)
+
+parse.y
+ - changed parse_string_to_word_list to turn off alias expansion

+ - changed parse_compound_assignment and parse_string_to_word_list to
+ allow reserved words in compound array assignments
+
+lib/readline/doc/rltech.texinfo

+
+config-top.h
+ - define KSH_COMPATIBLE_SELECT, with a comment about its meaning

+
+lib/readline/readline.h
+ - include rltypedefs.h
+
+ 12/19
+ -----
+lib/readline/complete.c
+ - slight change to mark-directories code to avoid adding a slash if
+ point is at the end of the line (rl_line_buffer[rl_point] == '\0')
+ and the previous character was a slash
+ - change printable_part to not return empty pathnames, which could
+ happen when completing filenames and a filename with a trailing
+ slash was passed as the argument. If the portion following the
+ trailing slash is NULL, ignore it and look for a previous slash.
+ If there's no previous slash, just return the filename argument
+ - new variable, rl_completion_mark_symlink_dirs, mirrors the value
+ of (user-settable with a variable) _rl_complete_mark_symlink_dirs
+ but may be modified by application-specific completion functions
+ when appropriate (set in rl_complete_internal and rl_menu_complete)
+
+lib/readline/readline.h
+ - extern declaration for rl_completion_mark_symlink_dirs
+
+pcomplete.c
+ - if one of the actions is CA_DIRECTORY, set
+ rl_completion_mark_symlink_dirs to indicate that we want the
+ trailing slash (might have to relax this)
+
+lib/readline/doc/rltech.texinfo
+ - documented rl_completion_mark_symlink_dirs variable
+
+lib/readline/doc/rluser.texinfo, doc/bash.1
+ - documented the fact that `complete -d' and `complete -o dirnames'
+ force readline to append a slash to symlinks to directories
+
+builtins/enable.def
+ - changed enable_shell_builtin to disallow enabling disabled
+ builtins in a restricted shell

+doc/Makefile.in
+ - new rule to make an `RBASH' file documenting the restrictions
+ imposed by a restricted shell
+
+expr.c
+ - broke the code that evaluates variables and returns results out
+ of readtok() into a new function: expr_streval()
+ - expr_streval() now performs the standard unset variable error
+ behavior if `set -u' has been executed and it's asked to look
+ up an unset variable
+ - broke the code that frees up the expression context stack into
+ a new function: expr_unwind()
+
+variables.c
+ - fixed bind_int_variable so it handles array element assignment,
+ so expressions like `b[7]++' and `b[0] = 42' work right
+ - new function, get_variable_value, returns the string value of
+ the SHELL_VAR * passed as an argument
+ - get_string_value now calls get_variable_value with a non-null
+ result from find_variable
+

+ - provide an extern declaration for strftime if HAVE_STRFTIME is
+ not defined and NEED_STRFTIME_DECL is
+
+lib/tilde/tilde.h
+ - header files should not include <config.h>
+
+parse.y
+ - replace code in decode_prompt_string that chops up value returned
+ by ctime(3) with calls to strftime -- as a result, the expansion
+ of \@ has changed slightly (since it depends on the locale)
+ - added new \D{format} prompt string escape; `format' is passed to
+ strftime(3). Empty format is the same as `%X' (locale-specific
+ representation of the current time)
+ - combined cases for '\\', '\a', '\e', and '\r' in same case branch
+ in decode_prompt_string
+
+doc/{bash.1,bashref.texi}
+ - documented new \D{format} prompt string expansion
+
+builtins/printf.def

+ with strlen()
+
+lib/sh/{fmtulong,fmtullong}.c
+ - changes from Paul Eggert to make more general
+

+ since they're not valid anymore
+
+ 12/27

+
+builtins/printf.def
+ - changes from Paul Eggert to just use intmax_t everywhere an

+ - remove getlong, getulong, getllong, getullong, since they're
+ no longer needed
+ - use a new type `floatmax_t' to print floating point numbers, the

+ - remove getdouble, getldouble, since they're no longer needed
+
+lib/sh/fmtumax.c
+ - new file, string-to-[u]intmax_t conversion, just includes

+Makefile.in, lib/sh/Makefile.in
+ - additions for fmtumax.c
+

+ - moved ansiexpand from parse.y to lib/sh/strtrans.c
+

+
+input.h
+ - new extern declaration for yy_input_name()

+ - use yy_input_name for error and other messages
+
+execute_cmd.c
+ - change shell_execve to make sure that the file is executable
+ before looking at the interpreter to find out why the execve()
+ failed (avoids misleading error message)
+
+lib/glob/glob.c
+ - move code that matches leading `.' and skips those filenames into

+ multibyte versions of that function
+
+ 1/7
+ ---
+subst.c
+ - more changes for multibyte characters
+
+print_cmd.c
+ - change semicolon() so it doesn't output a `;' immediately after a

+ error
+
+variables.c
+ - fix indirection_level_string to turn off set -x while evaluating
+ PS4
+
+ 1/8
+ ---
+builtins/set.def
+ - make -o options into one struct, instead of separate structs for
+ option names corresponding to flags and non-flag option names.
+ This has the side effect of sorting the option names in output
+
+lib/glob/glob.c
+ - new function, mbskipname(), multibyte char version of skipname()

+lib/readline/complete.c
+ - new function, rl_completion_mode (rl_command_func_t *func), returns

+
+lib/readline/readline.h
+ - new extern declaration for rl_completion_mode()

+lib/readline/doc/rltech.texinfo
+ - documented rl_completion_mode

+
+builtins/bashgetopt.c
+ - the `#' option specifier now means a required numeric argument,
+ not an optional one

+lib/readline/readline.c

+ with the text supplied as an argument
+ - new function, rl_replace_from_history, replaces readline line

+
+lib/readline/readlne.h
+ - new extern declaration for rl_replace_line
+
+lib/readline/doc/rltech.texinfo
+ - documented rl_replace_line
+
+lib/readline/{isearch,readline,search}.c
+ - use rl_replace_line and rl_replace_from_history where appropriate

+ - new function, find_local_variable, finds a local variable by name
+ at the current variable context
+ - in find_variable_internal, call find_local_variable before searching
+ any of the temporary environments if variable_context > 0 (meaning
+ we're in a shell function). This lets a local variable
+ override a variable whose value was passed in the `function
+ environment'
+
+ 1/15
+ ----
+variables.h, execute_cmd.c
+ - declare variables describing the temporary environments in
+ variables.h instead of in C files
+
+findcmd.c, builtins/setattr.def
+ - instead of calling find_tempenv_variable, use find_variable_internal
+ and check whether the returned SHELL_VAR * has the tempvar
+ attribute
+
+variables.c
+ - tentative change to lookup order in find_variable_internal so that
+ function local variables are found before variables in
+ function_env when executing a shell function
+ - change make_local_variable to handle making a local variable when
+ a variable with the same name already appears in one of the
+ temporary environments
+ - broke the body of make_var_array out into a new function:
+ static char **make_env_array_from_var_list (SHELL_VAR **vars)
+ - new function, make_var_array_internal, takes a hash table to look
+ in and a pointer to a mapping function and returns a char **

+ - make_var_array now just calls make_var_array_internal
+ - new mapping function, local_and_exported, returns all local variables
+ in the current variable context with the export attribute set
+ - new function, make_local_export_array, returns an environment-style
+ char ** array of exported local variables in current context
+ - change environment creation order in maybe_make_export_env to
+ add variables to the environment in opposite order that
+ find_variable_internal uses. This means that local variables in
+ shell functions override variables with the same name in the
+ function_env
+ - change make_local_variable to set the initial value of the
+ variable it creates to NULL to make the `is set' and `is null'
+ tests that the expansion code does work right
+ - change make_local_variable to inherit the value of a variable with
+ the same name from the temporary enviroment
+
+ 1/16
+ ----

+
+builtins/history.def
+ - make `history -n' increment the number of history lines in this

+
+jobs.c
+ - use PS_RUNNING, PS_DONE, PS_STOPPED values for `running' field
+ of a PROCESS
+ - find_pipeline and find_job now take an additional flags argument
+ that, if non-zero, means to find only running processes; changed
+ all callers
+ - changed calls to find_pipeline and find_job made from waitchld
+ to find only running processes
+ - find_pipeline takes a third argument: an int *. If it looks in
+ the jobs list to find the pid, and the arg is non-null, it passes
+ the job index back to the caller. Used to avoid calls to
+ find_pipeline immediately followed by find_job with the same PID
+
+nojobs.c
+ - a couple of changes to make sure that set_pid_status is never

+
+trap.c
+ - change trap_handler to longjmp to wait_intr_buf (set by wait_builtin)
+ if a signal is received for which a trap has been set during

+ - new variable to keep track of which signal caused the longjmp to
+ wait_intr_buf, set by trap_handler (wait_signal_received)
+
+builtins/wait.def
+ - set the return value of wait when a longjmp(wait_intr_buf, 1) is

+builtins/bind.def,doc/{bash.1,bashref.texi}
+ - changed the usage summary and help text to make it clear that any
+ readline command that may appear in ~/.inputrc may be supplied as
+ one of the non-option arguments to `bind'
+
+builtins/mkbuiltins.c
+ - added support for `-H' option, which means to write long documentation
+ for each builtin to a separate file in the `helpfiles' directory
+
+builtins/Makefile.in
+ - new target `helpdoc', just creates long doc files in helpfiles
+ directory
+
+lib/sh/zcatfd.c
+ - new file, with zcatfd(int fd, int ofd, char *fn); dumps data from
+ FD to OFD
+

+ - use internal_getopt for initial option parse, now that it supports
+ a leading `+'
+
+
+{configure,Makefile}.in, builtins/{Makefile.in,help.def,mkbuiltins.c}
+ - support for a new configure option, ``--enable-separate-helpfiles'',
+ moves the `long' help text to separate help files, installed by
+ default into ${datadir}/bash, one file per builtin. Off by
+ default -- it saves 47K, but it's only 47K, and it's in the text
+ segment
+
+flags.c
+ - build internal_getopt() option string argument from flags array at
+ runtime in shell.c
+
+shell.c
+ - new variable to control writing malloc stats at exit:
+ malloc_trace_at_exit, 0 by default
+
+lib/malloc/malloc.c
+ - heavily updated:
+ o partial page allocated on first call to malloc to make
+ subsequent sbrks page-aligned no longer wasted
+ o begin and end range guards are now the same value: the chunk
+ requested
+ o coalescing code was changed to attempt to coalesce first two
+ adjacent blocks on the free list; enabled by default
+ o blocks of size 32 are now candidates for larger block
+ splitting, since 32 is the most popular size
+ o blocks of size 32 are now candidates for smaller block
+ coalescing
+ o the IN_BUCKET check was changed to just make sure that the
+ size isn't too big for the bucket, since the `busy block'
+ checking code may increase the bucket by one or more,
+ meaning that the old check would fail and cause a panic when
+ a chunk allocated in such a way was freed
+ o bin sizes are now precomputed and looked up in an array
+ rather than being computed at runtime
+ o moved the _mstats declaration here to avoid the stats code
+ being linked in even when no stats functions were called
+ (only matters if MALLOC_DEBUG is defined)
+ o malloc now keeps track of the address of the top of the heap
+ and will return large chunks to the system with calls to
+ sbrk with a negative argument when freeing the top chunk.
+ Two thresholds: LESSCORE_FRC means to unconditionally return
+ memory to the system; LESSCORE_MIN means to return memory if
+ there's at least one block already on the free list
+
+lib/malloc/mstats.h
+ - stats struct now keeps track of number of block coalesces by bin,
+ and the number of times memory was returned to the system by bin
+
+lib/malloc/stats.c
+ - trace_malloc_stats now takes a second argument: the name of the file
+ to write to. The first `%p' in the template file name is replaced
+ by the pid

+configure.in, config.h.in
+ - check for getservent(), define HAVE_GETSERVENT if found
+
+bashline.c
+ - punt immediately from bash_servicename_completion_function if
+ HAVE_GETSERVENT is not defined (cygwin seems to not define it)
+ - include "input.h" for extern save_token_state() and
+ restore_token_state() declarations
+ - change bash_execute_unix_command to call parse_and_execute with
+ SEVAL_NOHIST flag so the command doesn't get saved on the history
+ list
+ - change bash_execute_unix_command to save and restore the current
+ command line count and the token state (last_read_token, etc.).
+ Everything else is saved by either parse_and_execute directly or
+ the call it makes to push_stream(). The shell_input_line stuff
+ doesn't need to be saved and restored; it's not computed until
+ readline() returns
