(Then why are we still talking about 'file'?)

Not sure it will help.  Example:

  $ file --mime-type -k -b lisp/international/uni-bidi.el
  application/octet-stream

Looks like there are some fundamental problems in 'file' that make it
not ideal for this purpose, to say the least.  Which, to me, just
reiterates what I already said up-thread: we should allow users to
override what the system-level tools provide, because they will never
be 100% satisfactory for our needs.
