.git/hooks/post-checkout for logging branch changes. Will mine this to see what sort of frecency map would be useful for finding "hot" branches

post-checkout hook provides the raw SHA1 for previous_head and current_head. At first I tried to turn those back into branch names, but that was error-prone (could be the tip of multiple branches). But then realized I could get the branch info from the new branch via rev-parse, since post-checkout runs after the checkout is complete (by definition).
git rev-parse --abbrev-ref HEADis the preferred way to get the current branch using git plumbing.
