I stumbled on this: https://gist.github.com/myusuf3/7f645819ded92bda6677
It describes how to delete a submodule. Still, even `git rm
<submodule>` leaves stuff behind.
How about a `git submodule rm` command (or similar) that *removes
everything* and stages it? It would be the complete opposite of `git
submodule add`.
