As I replied to the other email, I don't think we want to do this.

As "rel" means relative, I think it makes more sense to keep it as is, and
not have it just be from the data section. That may be even more confusing.

But I'll wait for Beau to answer.

Note, I added both your and Kees patches to my queue and I'm currently
testing it. You can see what I'm testing here:
