+       * info/search.c (skip_line): Remove unused function (which had a
+       useless null pointer check in it.) (Report from Hans-Bernhard 
Br\xF6ker.)

        * info/indices.c (next_index_match): Return a value instead of
        passing a pointer to a value to be set so that it is clear that
        calling code does not depend on an uninitialized value.  All
