I know. I'm the author of one of those bugs. I considered updating the
inflate loop in get_data() to support this throw-away mode but was
afraid I may make the same mistake like in index-pack again. I'll
probably drop this patch and think if I can unify inflate loop (for
other places too, not just unpack-objects).
