PCL-CVS: M-x cvs-update vs. key binding in *cvs* buffer

`M-x cvs-update RET' prompts for a directory and creates a *cvs*
buffer.  Do `M-x cvs-update RET' in the *cvs* buffer.  Again, it
prompts for a directory.

Now eval (global-set-key (kbd "C-c v u") 'cvs-update).  Then, when
pressing `C-c v u' in the *cvs* buffer, it won't ask for a directory.

I'd expect `cvs-update' to behave the same, no matter how it is called
(M-x vs. key binding).

It seems that `cvs-query-directory' tries to figure out if it was
called via M-x.  But I don't quite understand the purpose.

--8<---------------cut here---------------start------------->8---
(defun cvs-query-directory (msg)
  ;; last-command-char = ?\r hints that the command was run via M-x
  (if (and (cvs-buffer-p)

           (not current-prefix-arg)
           (not (eq last-command-char ?\r)))
    (read-directory-name msg nil default-directory nil)))
--8<---------------cut here---------------end--------------->8---

Bye, Reiner.
