        * gtk/gtktreeview.c (gtk_tree_view_set_search_equal_func): Mention
        GtkTreeViewSearchEqualFunc return value oddity here as well.

        * gtk/gtktreeview.c (gtk_tree_view_search_equal_func): On failure
        to get a string to compare to, return TRUE (no match), not
        FALSE (match). Handle %NULL string values gracefully.
        Remove unused variable. (#135962, Mark McLoughlin)
