Oh, I remember now, but I thought that those pactests "decide" not to resolve
that conflict [Note: I used the word 'autoresolves' here:
http://www.archlinux.org/pipermail/pacman-dev/2007-August/009078.html];-) And I
never could get myself to read that whole messy part in sync.c, however I saw
that pacman _can_ remove packages from the target list.

I would be happy if only the comment would be outdated ;-) Hopefully the whole
part around that comment never runs (otherwise it breaks some depends), so it
can be removed [line 504-554, 577-587(?)].
So the current sync.c is not so dangerous as I thought, however that is very
ugly (IMHO): [asked variable is unneeded, sync1003.py still fails]
