* subversion/libsvn_ra_serf/util_error.c
  (svn_ra_serf__wrap_err): Wrap ERR later since the incumbent pointer value is
    needed to set its ->message member correctly; it was set to "APR does not
    understand this error code"  at line
    54:  err = svn_error_create(status, NULL, NULL);
    because STATUS was neither a Subversion error code nor an APR one, and is
    being overriden in lines 89:96.
