vm-mime-charset-completion-alist needs updating

Dear Julian, do you think you can take a look at this bug?

Why give it as an explicit list? Why not compute it from one of the
other alists that have just been listed/computed. E.g

(defconst vm-mime-charset-completion-alist
  (mapcar 'car vm-mime-mule-charset-to-coding-alist))

For FSFmacs, those previously computed values ought to be enough, I
think. It's more complex for XEmacs, but how many of us are there?

>(defconst vm-mime-charset-completion-alist
> (mapcar 'car vm-mime-mule-charset-to-coding-alist))

Sorry, that should have read

(defconst vm-mime-charset-completion-alist
  (mapcar (lambda (a) (list (car a)))
    vm-mime-mule-charset-to-coding-alist))

Thanks Julian. That did the trick!
