Fix #131418.

2004-01-19  Federico Mena Quintero  <federico@ximian.com>

	Fix #131418.

	* gtk/gtkfilechooserdefault.c (set_select_multiple): New helper
	function.
	(gtk_file_chooser_default_set_property): Use
	set_select_multiple().  Also, re-set this mode to single if the
	file chooser is set to Save mode.
	(entry_activate): Handle the case where the entry is completely
	empty *and* its current folder does exist.  Also, there is need to
	test for select_multiple here now that we ensure that it won't
	happen during Save mode.
