I've worked on git diff --recursive a bit myself, along with some
simpler use cases (git ls-tree --recursive) as POCs. I think some of
the needs there begin to have ui implications which could be
high-friction. I really want to finish it someday, but I've been too
busy lately at $job, and now my experiments are all rather stale.

It would be a good discussion to have over at the git list (copied).
Heiko and Jens have laid some new groundwork in this area and it may
be a good time to revisit it.  Or maybe they've even moved deeper than
that; I have been distracted for well over a year now.
