Show usage string for 'git show-ref -h'
This only changes the behavior of "git show-ref -h" without any
other options and arguments.
"show-ref -h" currently is short for "show-ref --head", which
shows all the refs/* and HEAD, as opposed to "show-ref" that
shows all the refs/* and not HEAD.
Does anybody use "show-ref -h"? It was in Linus's original, most
likely only because "it might be handy", not because "the command
should not show the HEAD by default for such and such reasons".
So I think it is okay if "show-ref -h" (but not "show-ref
--head") gives help and exits.
If a current script uses "git show-ref -h" without any other
arguments, it would have to be adapted by changing "-h" to
"--head".
