	Fix #157787, reported by Jonathan Blandford:

	* gtk/gtkfilechooserdefault.c
	(gtk_file_chooser_default_set_current_folder): Don't leave a
	"trail" behind when set_current_folder is called explicitly.
	(gtk_file_chooser_default_update_current_folder): New function
	that is called to update the current folder in response to
	user actions.

	* gtk/gtkpathbar.c (_gtk_path_bar_set_path): Add a boolean
	keep_trail argument, and don't leave a "trail" behind unless
	it is set.
