[cvs-nhc98] With recent fixes for when Hidden/Forward chains are gener

malcolm: Fri May 17 16:28:55 CEST 2002 Update of /usr/src/master/nhc/src/hat/tools In directory hinken:/tmp/cvs-serv28588 Modified Files: artutils.c artutils.h Log Message: With recent fixes for when Hidden/Forward chains are generated, getResult() could fall into an infinite loop caused by a cycle in the result chain. The fix is to remember the most recent Hidden node encountered, and if we trip over it again, stop the cycle and return the Hidden.
