This is not true, according to Adobe's EPSF spec.  An EPSF file can
have a showpage, just like any PS file.  But when you want to include
an EPSF file in your PS document, you redefine showpage to be a no-op
before the EPSF file, then undefine this bogus showpage afterwards. 

This is described clearly by Adobe, and it is exactly the approach
taken by Borland's Sprint text formatter when you include an EPSF file
using @eps().  (Sprint is actually a nice way to learn about
PostScript, in addition to being a neat Scribe-type formatter.)
