It is actually still annoying to implement, since many things (at least commit-tree, branch) are unhappy with a non-branch in HEAD. Moreover, it's not as flexible as simply putting the commit sha1 into the HEAD, as you suggested. My suggestion allows only non-branch refs to be checked-out; however, it's likely somebody might want to git-checkout HEAD~10 or some other unnamed thing. -Peff - To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
