I had had a look at man magic and /usr/share/misc/magic - but what I'm
doing doesn't seem to fit (at least to my limited understanding).  I am
creating a file type "MUMPS Database". There is an entry
        # plus5:  file(1) magic for Plus Five's UNIX MUMPS
which doesn't describe what I'm doing.

Basically... does someone arbitrate src/cmd/file/magdir/* or do I
just plug in some random numbers?
