check-ref-format doc: --branch validates and expands <branch>jc/check-ref-format-oor
"git check-ref-format --branch $name" feature was originally
introduced (and was advertised) as a way for scripts to take any
end-user supplied string (like "master", "@{-1}" etc.) and see if it
is usable when Git expects to see a branch name, and also obtain the
concrete branch name that the at-mark magic expands to.
Emphasize that "see if it is usable" role in the description and
clarify that the @{...} expansion only occurs when run from within a
repository.
