Re: [PATCH v7 2/5] remove_subtree(): test removing nested directories

> Test removing a nested directory when an attempt is made to restore the
> index to a state where it does not exist. A similar test could be found
> previously in t/t2000-checkout-cache-clash.sh, but it did not check for
> nested directories, which could allow a faulty implementation of
