[PATCH 0/6] git-rm absorbs submodule git directory before deletion

The "checkout --recurse-submodules" series got too large to comfortably send it out for review, so I had to break it up into smaller series'; this is the first subseries, but it makes sense on its own.

This series teaches git-rm to absorb the git directory of a submodule instead
of failing and complaining about the git directory preventing deletion.
 
It applies on origin/sb/submodule-embed-gitdir.

Any feedback welcome!

Thanks, Stefan
