Before, I had an empty config.mak and I also had the following .git/info/exclude (these are two worktrees I have checked out):

	/jch
	/patches

aside from that, I don't think I've changed anything else. Anyway, to double-check that it wasn't my setup that was broken, I ran

	cd ..
	git clone git git2
	cd git2
	make configure
	./configure
and then followed the rest the steps and I could still reproduce it.

I don't have NO_GETTEXT on Mac but I don't think it affects anything.

Looks correct to me. I don't see why this wouldn't reproduce. I'll send you more information if I figure anything else out.
