v2.1.5.9

And another issue that I have not noticed, in a tiny change of Update behavior. Sorry for all those updates, but I do not do testing on everything, just on stuff I think could break a lot (have you seen a bugfix for the ABS build magic? I haven’t. Well, the validation fix was partially related to the ABS magic, but it was detected during a run of pb -S with an inexistent package that I thought might exist. I actually revised all the changes that happened since 2.1.5.5 (a release without those bugs) and I think I’m done with everything now.
