I'm interested of course in making life easy for project admins when
they need to tell testers how to get code to test out of git.  It'll be
nice to able to say:

	"Install git, then run
	git clone git://ourproject.com/ourproject.git
	cd ourproject
	git checkout <version you want>
	"

Instead of having to say

	"Install git, then run
	git clone git://ourproject.com/ourproject.git
	cd ourproject
	git checkout -b FOO <version you want>

	Then if you later need to check out another version, run
	git reset --hard <other version>
	"

I suppose <version you want> will typically be either some tagged
release or the latest head.  But it's not that farfetched to imagine
asking someone to test version 01997b4....

That should make it easy enough, though, I guess.
