New Revision: 8794

Modified:
   trunk/gs/src/simscale.c
Log:
For bug 689888.  This fixes the hang in the while loop.  If end of file occurs during the reading of the stream it is passed along by the filter.  However, proper output does not occur due to a different issue.  Another bug was opened related to this postscript noncompliance of string reading reuse in imaging operators.  See 689889.
