How do I "check back" to this version?  What git command do I use for this?  I tried

	git checkout f88dacd7e55e94c64a6cd103c81f9bccdb99601a

but this doesn't work because this "reference is not a tree".  When I

	git clone http://github.com/ianhinder/Kranc/commit/f88dacd7e55e94c64a6cd103c81f9bccdb99601a

then the error is that the "remote HEAD refers to nonexistent ref".
