Yes, functions look ok now as the sense - they are just moved up with no 
modifications, but the patch itself looks as broken to me as it originally 
was... Please, look 2 lines up - where you add your lines.

Indeed.
I don't know how that could happen. I would have sworn they were in the correct
place, then I rebased / solved conflicts, and ... messed up.

That would be for the v3, and I'll inspect the mails before sending.

Cheers.
