I probably should have mentioned, my run (in all cases) was:

	git rev-list HEAD -- Makefile 2>/dev/null

cheap, a file that exists pretty much everywhere, and that triggers the path limiter in the revision walking code.

BTW, I discovered by accident tonight that this works:

	cp git-rev-list ../git-1444
	../git-1444 rev-list

which is so not something I would have expected. :-) I honestly expected the wrapper to puke and say it doesn't know what command 1444 is.
