Here's a patch to add the old text to conflict marking,
as discussed on the mailing list.
How does this behave when you have nested or other fancy conflicts?
There are two cases here:
(1) Nested conflicts where all the conflicting changes are recorded. Then
you previously just got one set of conflict markers, often with more than
two "result" choices. That continues to be the case; this patch just adds
the "old" version at the top like with the simple case.
(2) A conflict where there were already unrecorded conflict markers. Here
you previously ended up with nested sets of conflict markers that were
typically completely unusable. I imagine that's still the case, though now
that the old text is an explicit part of the conflict markers, and the
unrecorded change is precisely against the old text, it might make for
more predictable results. Still likely to be useless though!
I don't have any specific experience of (2), I could test it out if you
think it's important.
