2008-07-21  Michael Natterer  <mitch@imendio.com>

	* gtk/gtktoolbar.c (gtk_toolbar_class_init): use the simpler
	g_signal_override_class_handler() instead of
	g_signal_override_class_closure().

	* gtk/gtktextview.c (gtk_text_view_class_init): ditto.

	(gtk_text_view_compat_move_focus): chain up using
	g_signal_chain_from_overridden_handler() instead of the generic
	g_signal_chain_from_overridden() which needs manual fiddling with
	millions of GValues.
