Hi Thomas,

It does look cleaner now. Can I ask you to add a comment near the
declaration of got_offsets on how to use it, meaning the shifting required.
User should know how to use a value without having to search for current
usages.

Other then that, looks OK to me. BTW, I did not check correctness, just
reviewed the style and logic.

Miki.
