[PATCHv2 0/9] Resending sb/submodule-recursive-fetch-gets-the-tip

This is a resend of sb/submodule-recursive-fetch-gets-the-tip, with all feedback addressed. As it took some time, I'll send it without range-diff, but would ask for full review.

I plan on resending after the next release as this got delayed quite a bit, which is why I also rebased it to master.

Thanks, Stefan
