That makes "%!" even less discriminatory than your last proposal. The
PostScript magic is _far_ too lenient.
I find strings like the following:
%!PS-Adobe-2.0
The Ghostscript example files (created manually, apparently) start
with
%!
and nothing else. I think it perfectly feasible to detect their
document type on the file name alone.
EPS files seem to start with something like
%!PS-Adobe-2.0 EPSF-2.0
So I'd propose making the magic string for PostScript at least
%!PS
While it may be conceivable to also allow %! on a line of its own, I
would judge that too weak for content-based detection.
