Unfortunately, POSIX file's -i means something different (spit
out one of a very short list of short file types that aren't
what we want, see "man 1p file" on Linux).  And it doesn't have
an option to spit out the MIME type.  So we could use it, but
only with a configure check to determine that it does what we
need.  If not available, we could look for mime.types, and so

Currently, we use the associations in the user's .mh_profile
and etc/mhn.defaults, which are greatly enhanced in the
upcoming nmh 1.5 as a result of your report.  Of course, it
would be much better to rely on system capabilities.  Some
day . . .
