	* gtk/gtkentrycompletion.c (gtk_entry_completion_class_init):
	Document that inline completion requires text-column to be set.
	(gtk_entry_completion_compute_prefix): Return NULL if text-column
	is not set.

	* gtk/gtkentry.c (check_completion_callback): Call
	gtk_entry_completion_complete() before inserting the prefix,
	otherwise the prefix may depend on (random) state of the
	filter model.
