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.
