Well, it does do that, which is the really weird part:

(defun gnus-button-url (address)
  "Browse ADDRESS."
  ;; In Emacs 20, `browse-url-browser-function' may be an alist.
  (if (listp browse-url-browser-function)
      (browse-url address)
    (funcall browse-url-browser-function address)))

It does the 'right' thing if it is a list, but not if it is just a
function.  Deeply weird.
