	* gtk/testtext.c (create_buffer): Add missing NULL on
	valist.

	* gtk/gtkcheckmenuitem.c (gtk_check_menu_item_class_init): Fix
	c-n-p problem with INCONSISTENT property.

        [ Patch from Havoc Pennington  <hp@redhat.com> ]

	* gtk/gtkentry.h (struct _GtkEntryClass): add same populate_popup
	hook.

	* gtk/gtktextview.h (struct _GtkTextViewClass): add populate_popup
	signal as a hook for extending the default popup menu

	* gtk/gtkimmulticontext.c (gtk_im_multicontext_append_menuitems):
	use radio menu items for the input method menuitems

	* gtk/gtkimcontextsimple.c (check_hex): do better validation of
	inserted unicode from Ctrl-Shift-hex input method

	* gtk/gtktextbtree.c (_gtk_text_btree_insert): remove utf8
	validatation here, already done at GtkTextBuffer level.

	* gtk/gtkwidget.c (gtk_widget_class_init): add binding set, add
	popup_menu run action signal and Shift+F10 and Menu keybindings.

	* gtk/gtkentry.c: implement a default handler for popup_menu

	* gtk/gtktextview.c: implement a default handler for popup_menu

	* gtk/gtkmenu.c (gtk_menu_popup): select first item if popup is
	from a key event

	* gtk/gtklabel.c: remove "trailer" cruft
