  oops, it seems this is only in the latest pu branch of git. If you are
not brave enough for that, you will need to use the prefix facility of
checkout-index instead, and it'll take much longer:

	git-read-tree $commit
	git-checkout-index -a --prefix=r1/
	rm .git/index
	cg-add -r r1/
	rm -rf r1
	.. then proceed with git-cat-file etc ..

  Note that I'm not sure when which feature was introduced. Your best
bet is to just use the latest stable GIT/Cogito versions.
