I couldn't reproduce after cloning with v1.6.6.3 (which creates ".git"
as a directory in the tree). Is it possible for you to bisect (or
perhaps share with us the broken example)?

I checked the release notes so far, and they do not say the old submodules 
from git 2.16- were no longer supported, so I assume it is a bug?

I don't think it was intentional. +cc Stefan for submodule expertise.
