This is what the code does:

#+begin_src 
(cond ((memq answer '(?? ?\C-h))
               (ask-user-about-supersession-help)
               (setq answer nil))
              ((eq answer ?r)
               ;; Ask for confirmation if buffer modified
               (revert-buffer nil (not (buffer-modified-p)))
               (signal 'file-supersession
                       (list "File reverted" fn)))
              ((eq answer ?n)
               (signal 'file-supersession
                       (list "File changed on disk" fn))))
#+end_src

So, nothing happens when we press ?n.
