	* gtk/gtkentrycompletion.c (gtk_entry_completion_popup): remove
	the reset of first_sel_changed, as after the first popup the treeview
	will always have a row selected and will thus not focus_to_cursor.

	* gtk/gtkentry.c (keyval_is_cursor_move): new function to determine
	whether the keyval should move the completion selection cursor (used
	to avoid ending up with extreme cluttered code), also added
	all KP_ equivalents of the keys here,
	(gtk_entry_completion_key_press): Keynav tweaks based on comments
	from Dave Bordoley and Marco Pesenti Gritti; add the -1 state
	as possible current selection, implement Home/End keys, modified
	the down key to stop cycling. Maybe page up/down should be implemented
	at some later time.
