bug#1183: 23.0.60; ediff-buffers is broken

[Drew Adams]

emacs -Q
 
Visit both the bookmark.el file from this installation (see below) and
a copy of bookmark.el from CVS for today, 2008-10-16.
 
The only difference between the two files is in fact this text which
was added to the CVS version near the end of the file, just before
run-hooks:
 
(defun bookmark-unload-function ()
  "Unload the Bookmark library."
  (when bookmark-save-flag (bookmark-save))
  ;; continue standard unloading
  nil)
 
You can see this by using ediff in Emacs 22, 21, or 20 - or by using
diff.
 
However, ediff-buffers shows the entire buffers as a single diff, and
hitting `*' to refine that diff has no effect at all. IOW,
ediff-buffers is now useless for seeing the differences between these
two files.
