Sorry, but I completely forgot about this three-month old topic (the last
discussion was early November last year).

How does this compare with Tim Henigan's "diffall"?  I think the problem
these two topics try to address is the same, and their approach may be
similar enough that having one consolidated effort might be worth it.

I seem to have suggested during the previous review round of this series
the same thing I suggested to Tim, that we _might_ want to instead have
the logic to populate the two temporary trees on the core side with a new
external diff interface.
