	* src/commands.c (cmd_search_replace_update_after_action): New
 	function.
	(cmd_search_replace_undo, cmd_search_replace_redo,
 	cmd_search_replace_do): Call
 	cmd_search_replace_update_after_action.
	(cmd_search_replace_do_cell): Change to work on entered text which
 	is, we believe, what XL does.
