another bug in gs 8: it includes subsets of the standard postscript fonts
when distilling grops output - it doesn't seem to recognize them.
Telling it not to subset fonts at all leads to disastrous results (i.e.,
files with no font information whatsoever, and all test replaced by black
dots).  This bug is new with gs 8.
