FWIW, I consider this not a good UI.  Having point one column to the
left or to the right of where you want to be is quite frequent, so
making a key sequence produce a very different effect depending on
that is far from being the best idea, IMO.

To me, this tells that these two modes, and the user expectations and
habits to go with them, are simply incompatible, and we shouldn't try
mixing them.  If someone wants a diff-mode-like outline mode, let's
make such a mode, and leave the original diff-mode alone.
