+       * util/texi2dvi (filter_files): Ensure that this function does not
+       make any non zero return status when the list of new xref files is
+       empty. Otherwise that causes a prematurate exit of calling
+       function, notably run_index. Remember texi2dvi is running under
+       set -e regime.
