This new patch is better.  This is already good.  There is one more tweak that
maybe could make it even better: with this latest patch, if the user types =
<RET> in the backup file then Emacs says
   Attempt to compare the file to itself

Wouldn't it be better if dired-diff refused the minibuffer input if it is not
a valid file?  This way, if the user types = <RET>, Emacs will display "[no
match]", which would be more precise.
