GtkFileChooserEntry: handle slow folders by not autocompleting when the cursor is not at the end of the text
2009-01-22  Federico Mena Quintero  <federico@novell.com>

	* gtk/gtkfilechooserentry.c (autocomplete): Relax the assertion;
	just do nothing if the folder is not loaded or if the cursor position
	is not at the end of the text.  A very slow-to-load folder can get
	us into the latter state if the user starts typing first.
