  Log:
  SVN rev 185100 on 2008-11-19 18:06:29Z by hrs
  
  MFC: Add workaround for a back reference when no corresponding
  parenthesized subexpression is defined.  For example, the
  following command line caused unexpected behavior like
  segmentation fault:
  
   % echo test | sed -e 's/test/\1/'
