Yes, sorry :-(  I apparently managed to forget the reversing here and
never noticed.  I'll make a fixed patch 4/6 today.

Well, as I said earlier in the thread I'd hate to reverse the
direction of plain "{reset,checkout,stash} -p" because I want them to
show hunks that match visually.

But then my mental model of "checkout other -- file" is already of the
sort "fetch me the contents of 'file' from 'other'", and I think I use
it about as frequently in a forward as in a backward application.  And
I just felt it would be easier to mentally go over the consequences if
it shoed the diff the other way.

(I'm sufficiently confused about which way is back that I think I'll
just stop saying "backward"...)

Should be doable, I'll look at it.
