You misunderstood.  My suggestion, to which Stefan agreed, was that
_in_addition_ to showing any textual differences, ediff-buffers would
display a warning saying that the buffers _also_ differ in the way
they will be encoded on their disk files.

In the extreme case that the text is identical, only the warning will
remain as the single sign of a difference.

After Ediff is fixed, you will see the diffs you see in Emacs 22, plus
a message saying that the EOL format is different.
