  <2> show only names and the nature of change, but not actual
  diff output.  --name-status disables usual patch generation
  which in turn also disables recursive behavior, so without -r
  you would only see the directory name if there is a change in a
  file in a subdirectory.

"Of course" one knows that "git diff <tree-ish> <tree-ish>" is
git-diff-tree in disguise, and accepts git-diff-tree options.

By the way, I was thinking about extending --numstat output to include
also status. Current --numstat output is ill fitted to deal with renames
and copies, at least ill fitted for machine consumption of renames
output; it uses "old_name => new_name" as a filename for renames. While
it would be fairly easy to put pre- and after-rename names separated
by TAB, and quoted if needed (including embedded TAB character in
the filename, which would be quoted as \t instead) without breaking
anu current --numstat output parsers (although I don't think any of
them uses -M/-C), it would be hard to do the same for --numstat -z output.
A solution (not best, I admit) would be to use NUL NUL to separate pre-
and post-image filename, but I think it would be best to add new
--numstat-extended format to git-diff.

P.S. Is binary diff output described somewhere?
