[cvs-nhc98] patch applied (hat): With recent fixes for when Hidden/Forward chains are generated,

Fri May 17 07:28:55 PDT 2002 malcolm * 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. M ./src/hattools/artutils.c -8 +25 M ./src/hattools/artutils.h +1
