PostScript interpreter itself. The problem is that some (most?) PostScript
level 1 interpreters (such as the Apple Laserwriter Plus!) don't define
the ISOLatin1 encoding vector AND don't define a character called `minus'.
Therefore, substituting `hyphen' (which is always defined) for `minus',
isn't really `wrong' aesthetics not withstanding! :-) A conditional patch
would (IMHO, say Jeremy) be overkill: the only people that would be
interested in it are typographers, and they probably don't use mp to
format their mail anyway.
