So the code should be:

   /* sending a log msg from server to client */

   if (is_valid_utf8 (msg) && svn_xml_is_xml_safe (msg))
        send_message (escape_xml (msg));
        send_message (fuzzy_escape (msg));

then? (This assumes that fuzzy_escape() produces totally XML-kosher
data, naturally.)
