Log:
GtkFileChooserEntry: fix the computation of 'complete but not unique' and appending a '/' to unique directory names
2009-01-22  Federico Mena Quintero  <federico novell com>

	Fix the computation of "complete but unique" in
	GtkFileChooserEntry.  Fix the case where "/" was not appended to a
	unique directory name during explicit Tab completion.

	* gtk/gtkfilechooserentry.c (maybe_append_separator_to_file):
	Return whether anything was appended as well as the new string
	itself.
	(find_common_prefix): Oops, only turn on
	is_complete_not_unique_ret if we had a unique match!
	(append_common_prefix): If we appended a directory separator, we
	*did* expand the common prefix, so we are not in the "nothing
	inserted" case.
