 Replying to [comment:2 sascha_silbe]:
 > Can we (i.e. I) have a go at this now that 0.86 has been branched off?
 Do you want to review my changes or should I commit them (one commit per
 type of change, i.e. number of empty lines between blocks, overlong lines,
 ...) directly?

 Do you see any advantage on doing several commits instead of only one?

 I think we should go through the review queue now, then do this cleanup
 and push it once for all.
