	* gdk/gdk.c (gdk_arg_debug_cb) (gdk_arg_no_debug_cb): A
	GOptionArgFunc should return gboolean and take also a GError
	pointer parameter, so make these two functions do that. Return
	FALSE (and set the GError) if the parsing of the debug string
	failed completely. Note that g_parse_debug_string() doesn't really
	have any way to return parsing status, and accepts partially
	incorrect strings, though.
