I started from the 78ec8e commit then cherry-picked and squashed commits that have been done in master since then, except the bad commits that overwrote the tree (in master) with the tree in maint. This commit also bumps the version number to 7.8.06. The only "fix" that was made between 78ec8e and the previous commit is e0072f which has been reported to break stuff.
