In git, a Ref can be a Sha, or a Branch, or a Tag. I added type aliases for those. Note that this does not prevent mixing up of eg, refs and branches at the type level. Since git really doesn't care, except rare cases like git update-ref, or git tag -d, that seems ok for now. There's also a tree-ish, but let's just use Ref for it. A given Sha or Ref may or may not be a tree-ish, depending on the object type, so there seems no point in trying to represent it at the type level.
