vc-cvs-checkout-model can fail

[Christoph Conrad]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.

Your bug report will be posted to the address@hidden mailing list.

Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:

vc-cvs-checkout-model: if CVSREAD isn't set and the file does not exist
(file-attributes file) => nil and so string-macth must fail.

(defun vc-cvs-checkout-model (file)
  "CVS-specific version of `vc-checkout-model'."
  (if (or (getenv "CVSREAD")
          ;; If the file is not writable (despite CVSREAD being
          ;; undefined), this is probably because the file is being
          ;; "watched" by other developers.
          ;; (If vc-mistrust-permissions was t, we actually shouldn't
          ;; trust this, but there is no other way to learn this from CVS
          ;; at the moment (version 1.9).)
          (string-match "r-..-..-." (nth 8 (file-attributes file))))
