The last item of the `browse-url-filename-alist' variable defined
in browse-url.el seems to be wrong.

--8<---------------cut here---------------start------------->8---
browse-url-filename-alist is a variable defined in `browse-url.el'.
Its value is
(("^/\\(ftp@\\|anonymous@\\)?\\([^:]+\\):/*" . "ftp://\\2/";)
 ("^/\\([^:@]+@\\)?\\([^:]+\\):/*" . "ftp://\\1\\2/";)
 ("^/+" . "file:/"))
--8<---------------cut here---------------end--------------->8---

I think it should be ("^/+" . "file:///").  How about this
workaround?

(eval-after-load "browse-url"
  '(let ((file (rassoc "file:/" browse-url-filename-alist)))
     (if file (setcdr file "file:///"))))

The value has never been changed since it was provided in Emacs
20.3.  You may be the first person who used it.
