why do "git log -h" and "git show -h" print the same thing?

  maybe this is deliberate, but it's confusing that, with git 2.17.0,
the output of both "git log -h" and "git show -h" is exactly the same:

$ git log -h
usage: git log [<options>] [<revision-range>] [[--] <path>...]
   or: git show [<options>] <object>...

    -q, --quiet           suppress diff output
    --source              show source
    --use-mailmap         Use mail map file
    --decorate-refs <pattern>
                          only decorate refs that match <pattern>
    --decorate-refs-exclude <pattern>
                          do not decorate refs that match <pattern>
    --decorate[=...]      decorate options
    -L <n,m:file>         Process line range n,m in file, counting from 1
$

is that what's *supposed* to happen?
