Sorry about the repost ("fat fingers on C-c").

What do you mean by a "catch-all coding system"?

    >> How about something like:

    >> (if (featurep 'mule)
    >>     'emacs-mule ; or some other catchall
    >>   'buffer-file-coding-system)

This is definitely wrong.  'emacs-mule doesn't exist in XEmacs (this
is the internal coding used by Mule, and only a very few other
applications support it), and coding systems don't exist at all in
non-file-coding XEmacs.  That means almost all non-mule installations
on Unix.  I would guess that any place where coding systems are used
will have to be rewritten to test for (featurep 'mule) instead of
trying to use a generic coding system.

If you don't like that, I'd say just require file-coding.  Let's ask
Vin how he feels about it, maybe we should think about moving to
defaulting to file-coding in 21.4.
