The comparison with textual "undefined" smelled fishy and I ended up
looking at the implementation of currentGitBranch().

    def currentGitBranch():
        return read_pipe("git name-rev HEAD").split(" ")[1].strip()

Yuck.  I know it is not entirely the fault of this patch, but
shouldn't it be reading from

    $ git symbolic-ref HEAD

and catch the error "fatal: ref HEAD is not a symbolic ref" and use
it as a signal to tell that the HEAD is detached?
