The native format doesn't _need_ to use "git ls-remote", because the 
native format does it on its own.

In fact, "git ls-remote" actually uses the pack transfer protocol to 
figure out what the remote heads are (it just then doesn't _ask_ for 
anything), so in many ways you can see "git ls-remote" as being just a 
helper around the basic clone/pull protocol.

So "git clone" ends up doing the equivalent of a git ls-remote to populate 
the initial local heads and tags. It's just that for the native protocol, 
it all happens together in one burst.
