It's hard to tell what's wrong with the code based on this warning,
though.  (It says save-excursion is "defeated", but buffer, point, and
mark still seem to be getting restored.  So what's the hidden danger?)
 Maybe it should specifially say something like, "save-excursion +
set-buffer could possibly be replaced by with-current-buffer."
