[PATCHv2 0/3] fix recursive submodule absorbing

In this second iteration, only absorb_git_dir_into_superproject is touched, which does the check if connect_work_tree_and_git_dir is needed.

Internally I also had a patch that converts is_submodule_populated to be gentle, but it is not needed here, so I dropped it before sending out.

Thanks, Stefan
