Okay, `git-http-backend` is listed in `git --list-cmds=main`.

That one doesn’t support `-h`.

    $ git http-backend -h >/dev/null
    fatal: No REQUEST_METHOD from server

and

    $ git http-backend -h 2>/dev/null
    Status: 500 Internal Server Error
    Expires: Fri, 01 Jan 1980 00:00:00 GMT
    Pragma: no-cache
    Cache-Control: no-cache, max-age=0, must-revalidate

git-filter-branch(1) prints a warning about “glut of gotchas”, waits 10 seconds, then prints usage to stdout.

    $ time git filter-branch -h >/dev/null

    real	0m10,058s
    user	0m0,023s
    sys	0m0,041s
