Mauro, I have put a daemon in place of the proof obligation that used to
be closed by % and that is no more. I have absolutely no idea why did it
change. Moreover, it seems trivially true, but I found no easy way to prove
it with the current results. Is there any?

But for that, all the file is repaired.
