Actually, what you want is in the reflog, no? So... parsing .git/logs/HEAD for the latest occurrence of "checkout: moving from " and then using everything up until the next space should give you the branch name, right?

It could be a SHA-1, though, if the last branch switch was from a detached HEAD, though.
