url: url-basepath

[T. V. Raman]

This function disappeared from the emacs 23 version of url at
some point.
It's used by W3, I'd like to see this function restored if
possible.

Here is the original code:
(defun url-basepath (file &optional x)
  "Return the base pathname of FILE, or the actual filename if X is true."
  (cond
   ((null file) "")
   ((string-match (eval-when-compile (regexp-quote "?")) file)
    (if x
        (file-name-nondirectory (substring file 0 (match-beginning 0)))
      (file-name-directory (substring file 0 (match-beginning 0)))))
   (x (file-name-nondirectory file))
   (t (file-name-directory file))))
