PEP8 fixes for sugar

[sascha_silbe]

pep8.py has lots of complaints for sugar. We didn't manage to get fixes for them checked in in time for 0.86, so need to do that for 0.88.

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?

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.
