Refine operational logging for svn log.
Refine operational logging for svn log.

* subversion/mod_dav_svn/reports/log.c
  (dav_svn__log_report): Make the log action parseable by replacing
    'all-revprops' with 'revprops=all' and '(REVPROPS...)' with
    'revprops=(REVPROPS...)'.  The old form wasn't quite parseable, as
    the (revprops list) may have been missing and the next item on the
    log line (perhaps the user agent) may have started with '('.
