Re: [PATCH 4/4] pack-objects: rewrite add_descendants_to_write_order() iteratively

This removes the need to call this function recursively, shinking the
code size slightly and netting a small performance increase.

Tricky.

As long as this is done after compute_write_order() populates
delta_sibling vs delta link in a consistent way, the new logic should
produce exactly the same result as the original code.

Thanks.
