[Python-ideas] PEP 8 update on line length

Not often. Once. But then I really really needed it :)

It was a case where we had an API change to a lib and many calls where long enough to be split on multiple lines AND the keyword argument we had to find was very generic AND it could exist in nested calls. Of course the last was really fine since we could ha e worked through the false positives manually. 

I also happen to have lots of experience with Parso so it was easy for me to write. Otherwise we would probably have a logged through the crappy way. 

It's pretty nice to have this is the tool belt though.
