In my use of git, I've noticed that "git status" is a lot better at
tracking moves and renames than "git diff", and this has recently
caused
me a lot of headaches because a large number of moves were made in a
single commit, and it was very difficult to figure out which moves
were
right and which were wrong.

I was using a fairly old version of git (1.7.11), but was able to
reproduce it on git 2.2.1.

Here's a reproduction recipe:

[...]

# Now "shift" the files
git mv 2 3
git mv 1 2

[...]

quoted

git commit -m "2=1;3=2;"

# Neither of these commands get it (but -C gets a glimmer of the
truth)
git diff -M --stat --summary HEAD~..
git diff -C --stat --summary HEAD~..

Ah, but did you try this:

  git diff -B -M --stat --summary HEAD~..

Yes, since f714fb84 (Enable rewrite as well as rename detection in
git-status, 2007-12-02) "git status" internally uses "-B -M".
