* subversion/libsvn_ra_neon/util.c
  (start_207_element, end_207_element): Add minimal doc strings.
  (multistatus_parser_create): Add a minimal doc string. Don't return a
    pointer to the created parser because it's attached to the request and
    that's all we need.
  (svn_ra_neon__simple_request): Remove the comment and type cast indicating
    that we don't use the return value from multistatus_parser_create().
