I wonder if you want to rephrase this, because 40-hex object name is
syntactically a valid branch name. It's (1) cumbersome to type and
(2) may not be what the user expects.
I have a mild suspicion that "git checkout -B @{-1}" would want to
error out instead of creating a valid new branch whose name is
40-hex that happen to be the name of the commit object you were
detached at previously.
I am not sure if "check-ref-format --branch" should the same; it is
more about the syntax and the 40-hex _is_ valid there, so...
