This though needlessly peeks into the raw refstore. Use branch=$(git
symbolic-ref --short HEAD) instead. See e.g. my
https://lore.kernel.org/git/patch-08.11-7fb8849ce66-20210423T072006Z-avarab@gmail.com/ (local)

I was about to say that doesn't work with a freshly initialized repo
without a commit yet, but I'm thinking of `git rev-parse --abbrev-ref
HEAD`.

I'll change it if I have to re-roll for another reason.
