`got` is an unusual name for this variable, and I don't really
understand what the word means in this context. Is there a reason not to
use the more usual `err`?

Is there a reason not to allow `--normalize` with `--branch`?
(Currently, `git check-ref-format --branch` *does* allow input like
`refs/heads/foo`.)
But note that simply allowing `--branch --normalize` without changing
`check_one_ref_format()` would mean generating *two* lines of output per
reference, so something else would have to change, too.
