Show usage string for 'git check-ref-format -h'

This only changes the behavior of "git check-ref-format -h" without any other options and arguments. This change cannot be breaking backward compatibility, since any valid refname must contain a /. Most existing scripts use arguments such as "heads/$foo". If some script checks the refname "-h" alone, git check-ref-format will still exit with nonzero status, and the only detrimental side-effect will be a usage string sent to stderr.
