Previously, when --verify was specified, show-ref would use a separate
code path which ignored --head. Thus, "git show-ref HEAD" used with
"--verify" (because the user is not interested in seeing
refs/remotes/origin/HEAD), and used with "--head" (because the user
does not want HEAD to be filtered out), i.e. "git show-ref --head
--verify HEAD", did not work as expected.
Instead of insisting that the input begins with "refs/", allow "HEAD"
when "--head" is given in the codepath that handles "--verify", so
that all valid full refnames including HEAD are passed to the same
output machinery.
