  Revision 1.9  2005-05-12 20:29:04  michael
  + Added maxpathlen constant (maximum length of filename path)

  Revision 1.8  2005/04/03 21:10:59  hajny
    * EOF_CTRLZ conditional define replaced with CtrlZMarksEOF, #26 handling made more consistent (fix for bug 2453)

  Revision 1.7  2005/02/14 17:13:31  peter
    * truncate log
