+       * util/texi2dvi (xref_files_changed): Call 'sorted_index_files'
+       to get a list of the sorted index files that should exist, and
+       if any of them are missing, go around another cycle of 
+       processing.

        * util/texi2dvi (filter_files): Comment changed.
        (add_all_filter): Do not print the argument of the file, so 
        using this with filter_files only prints secondary files.
