[Maxime Villard <max%m00nbsd.net@localhost>]

Hi,
I've added some bugs here:

	http://m00nbsd.net/ae123a9bae03f7dde5c6d654412daf5a.html#Unsorted-4

I don't have time to investigate, review and fix them. They don't seem all
easy to fix, so please make sure you can test/carefully review your changes,
as usual. Below is a summary, in case it inspires someone:
