In other words, if we do this in the state:

  $ git -C vim/bundle/fugitive describe --dirty

the submodule directory is not reported as dirty.

This is worth fixing.  I am leaning towards saying that `diff` is
wrong in this case, but I am OK to consider unifying the behaviour
the other way and making `describe --dirty` more strict.

Thanks.
