OK. Too late, but it has my ack. ;)

Aren't we using "git diff" for the second diff there nowadays?

Some people seem to think that is a good idea, but I generally do not
like using "git diff" between expect and actual (both untracked) inside
tests.  The last "diff" is about validating what git does and using "git
diff" there would make the test meaningless when "git diff" itself is
broken.

I think that is a valid concern. But ISTR that were some issues with
using GNU diff. Commit 5bd74506 mentions getting rid of the dependency
in all existing tests, but gives no reason.
