Interesting. That commit _should_ have just moved code around with no 
actual semantic changes.

Can you verify that undoing just that one commit makes current git (-rc9) 
work for you? Ie just try a

	git revert 266c2e0abeca649fa6667a1a427ad1da507c6375

on top of the current tree. I just want to check, because even after 
looking at that diff again, I'm not seeing what it could actually change.
