True. And `git-shell` is not a builtin, so it does not even matter with
regards to this discussion.

Even if upload-pack is not a builtin (and thus still has to be its own
executable), receive-pack *is*, so this does affect our current
discussion.

This is a real problem. And it is our own darned fault because we let an
implementation detail bleed into a protocol. We could have designed that a
lot better.

Of course we should fix this, though. There is literally no good reason
that I can think of why we should not change this to `ssh <host> git
upload-pack ...` (of course with an insanely long deprecation period).
