Not really an issue, but you're wrapping your text at ~60 characters.
The common use is to wrap around 70 to 80. Using Emacs, auto-fill-mode
or M-q does this automatically. If you use another text editor, it can
probably do that for you too.

I think this would deserve a test and documentation. Even though your
motivation is for an internal implementation, some users may want to use
the feature in 'git for-each-ref --format=...'.

You're silently accepting %(refname:shortalign=foo) and
%(refname:shortalign=). I think it would be better to reject such cases
explicitly.
