Oh, I just tried it and git now creates a local branch if you try to
checkout a remote branch with no local copy. I don't think it used to
do that.

You are checking out a local branch here, you need to merge or pull
the remote branch. You can tell when it's checking out a remote branch
because it says something like, "Branch develop set up to track remote
branch develop from origin."
