* 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.
