If we have checked out a commit instead of a branch name, git is in what’s known as “detached head” state.
This is what Travis does all the time — see the latest build output.
This means that we were never considered to be on the branch “master”, and therefore were never publishing bower-chosen.
We can tweak the git command we’re calling to support either checked out branch names or detached heads — as long as we’re at the commit for a commit that is the head of master, we’re peachykeen!
