Re: Magic MIME

[Richard Stallman]

    Emacs could follow the principle of graceful degradation here: if there
    is no necessary external command or mime database on the system, then
    it will provide less reliable result that will be no worse than the
    current without using the magic.mime based file type recognition.

Unless that gets us big benefits, it is better if we don't use it.
There is an advantage in keeping Emacs self-contained.
