In directory hinken:/tmp/cvs-serv7237

Modified Files:
	artutils.c 
Log Message:
Fix incorrect (cyclic) display of (non-cyclic) partial structures,
typically lists.  If the unevaluated part of the structure is an
ExpForward pointer to a Hidden, then we should stop at the next Hidden,
not clear the Hidden-detection flag.
