It does not help. The error in git-add--interactive is avoided, but the
failure in t2016-checkout-patch.sh is now:

expecting success:
        set_state dir/foo work head &&
        # the third n is to get out in case it mistakenly does not apply
        (echo y; echo n; echo n) | (cd dir && git checkout -p foo) &&
        verify_saved_state bar &&
        verify_state dir/foo head head

No changes.
not ok 13 - path limiting works: foo inside dir

and the same "No changes." happens in t7105-reset-patch.sh
