when tracking refs/heads/master instead of HEAD, you also get:
   * A submodule where HEAD is not pointing to refs/heads/master is
     "dirty-branch" or something.

This is handled by creating a GIT repository in this directory.
My current implementation needs some more magic by the user to add it to
the index, but I plan to change this to the way that GIT repositories
will be recognized as possible submodules.

This is on top of my TODO.

it's only update-index that has to know this.
Otherwise it would be implicitly updated and you would never get your
"changed but not updated" status as above.
