	Merged from gtk-2-6:

	Fixes #162358:

	* gtk/gtkfilechooserdefault.c (update_chooser_entry): Don't return
	immediately if we are in CREATE_FOLDER mode, so that we can fill
	the entry with the newly-selected folder.
	(gtk_file_chooser_default_set_property): Warn against turning on
	multiple selection for CREATE_FOLDER mode, or about setting that
	action while multiple selection is on.
	(update_chooser_entry): Change the entry's contents as well if we
	are in CREATE_FOLDER mode.  If nothing is selected, clear the
	chooser entry.
	(trap_activate_cb): Don't trap enter/space if modifiers are
	pressed.  This lets one use Ctrl-space to toggle rows in multiple
	selection mode.
	(gtk_file_chooser_default_should_respond): Clean up the if-chain
	mess of special cases by using an array to determine what to do.
	Also, for the save-entry case in CREATE_FOLDER mode, actually fix
	the bug where the file chooser would switch to an existing folder
	rather than confirming with it, and create the folder ourselves.
	(error_creating_folder_over_existing_file_dialog): New function.

	* gtk/gtkfilechooserentry.c (check_completion_callback): Only
	insert the common prefix if we are in an "open" mode.  Use a
	helper function.
	(append_common_prefix): New helper function; code moved over from
	check_completion_callback().
	(find_common_prefix): New helper function.
	(gtk_file_chooser_entry_focus): Append the common prefix if the
	user requests it explicitly.
