Okay, so where does a global save/restore go, in the context of EPSF?
(Don't tell me that we should assume the save/restore, as supplied by
the printer, because many people on microcomputers lack the proper
spooling software that sends ^D's at the end of the file.)  The restore
has to go in the trailer.  The save can't be in any of the pages.
Between the prologue and the pages?  But I want to lose the prologue
definitions too, if possible.  Comments?
