        * gtklabel.[ch]: Use a bit of the GtkLabel structure to
        remember that a pattern has been set.
        (gtk_label_set_pattern_internal): Don't do anything if
        a specific pattern has been set.
        (gtk_label_set_pattern): set the new bit to TRUE when
        setting a pattern, and recalculate everything if the
        pattern is unset. Fix gtk_label_set_pattern() not working
        anymore.  (#452861, Vincent Untz)
