	* gnome-keybinding-properties.c: (accel_edited_callback),
	(accel_cleared_callback), (start_editing_cb),
	(maybe_block_accels), (setup_dialog): stop widget accelerators
	from activating while the user is entering a new shortcut. This
	allows binding shortcuts that are used as accels in the capplet
	dialog, e.g. for the Help and Close buttons (bug #313228)
