	* exceptions.c (struct catcher): Delete saved_error_pre_print and
	saved_quit_pre_print.
	(catcher_init): Delete parameter errstring, do not override the
	pre_print strings.
	(catcher_pop): Do not restore the pre_print strings.
	(catch_exception, catch_exceptions_with_msg, catch_errors)
	(catch_command_errors): Update catch_init calls.
