I like your choices.

Why not return the Commit directly, and let the caller extract its
sha1 if that's what it wants?

You don't remove the old parse_rev() and git_id(), and particularly
the latter has a lot of callers. Meaning that the rest of StGit still
speaks the old syntax.

What if you have a branch or tag with the same name as a patch? This
will prefer the branch, which might not be the best choice.

You have an extra ] here.

Couldn't we kill this option? (And in the process, the branch argument
to git_sha1.)

Strictly speaking, this isn't so new anymore.
