That's what I would do, indeed.  Well, I'd use this if you need the
string form:

    (package-version-join
     (package-desc-version (cadr (assq 'matlab-mode package-alist))))

Yeah, it's a bit of a mouthful.  Most packages don't bother, and just
rely on `describe-package`, I think.

That said, there's nothing wrong with keeping it around; it just seems
redundant now that you have a "Version" header.  I mostly mentioned it
for the record, and in case you wanted to get rid of some possible
redundancy.

(Personally, I'm not sure if the `matlab-show-version` command is needed
either given that we have `describe-package`.  In emacs.git, we tend to
make such `foo-package-version` commands obsolete.)

Hmm, are you sure that you need it for MELPA even with the addition of
the "Version" header?

In any case, this is an extremely minor nit either way.
