* Makefile.in (utils.o): Update.
* top.c (in_user_command): New.
(command_line_input): Use input_from_terminal_p.
(input_from_terminal_p): Don't check caution. Handle
stdin == NULL for Insight.
* top.h (in_user_command, caution): New declarations.
* utils.c: Include "top.h".
(query, defaulted_query): Check caution here. Move the call
to input_from_terminal_p higher.
* cli/cli-script.c (do_restore_user_call_depth): Only decrement
the depth. Update in_user_command if necessary.
(execute_user_command): Don't clobber old_chain. Set
in_user_command. Let do_restore_user_call_depth handle
user_call_depth.
(read_command_lines): Check whether to prompt before calling
Insight hooks.
* tui/tui-hooks.c (tui_query_hook): Remove newly unnecessary
input_from_terminal_p check.
