+ possible changes
+ - new function that does the bulk of the work for
+ rltty_set_default_bindings: _rl_bind_tty_special_chars()
+ - change prepare_terminal_settings so that it can track changes to the
+ terminal special chars made by stty(1): unset the bindings with
+ rl_tty_unset_default_bindings before calling save_tty_chars, and
+ _rl_tty_set_default_bindings after, with the new values from
+ get_tty_settings(). This implements a long-standing request, most

+ of just the escape characters if the expansion appears between
+ double quotes or in a here-document (for simple variable expansions

+subst.c
+ - analogous changes to parameter_brace_expand_word to fix the same

+ - add a `quoted' argument to get_var_and_type, change callers

+
+lib/readline/histexpand.c
+ - don't call add_history in history_expand if the `:p' modifier is

+general.h
+ - new extern declaration for legal_alias_name

+ ---
+lib/readline/vi_mode.c
+ - in rl_vi_change_to, call _rl_vi_set_last with rl_numeric_arg instead

+
+lib/readline/rlprivate.h

+
+lib/readline/readline.h

+bashline.c
+ - new function for vi-mode completion, bash_vi_complete. Does
+ filename expansion as POSIX specifies, unlike the default readline
