This is correct code. But the hooks are only invoked if there is
actually a change to be made to the repository. The client end of the
push needs to for example create a new branch on the server side. Or
have a newer commit that is not yet at the server, and push that to a
branch on the server. Hooks don't run if the client and server are at
the same state.
