It turns out that this is handled through the url-file-handler stuff...

(defun browse-url-emacs (url &optional same-window)

[...]

  (let ((file-name-handler-alist
         (cons (cons url-handler-regexp 'url-file-handler)
               file-name-handler-alist)))
    (if same-window (find-file url) (find-file-other-window url))))

(browse-url-emacs "file:///tmp" nil)

Michael, do you know anything about this?  :-)  I'm wholly unfamiliar
with the url-file-handler stuff or how it's supposed to work.
