Hi @mindnect thanks for opening this. I can successfully reproduce this error. We will fix it for 4.2.2!
Please @steff456 take care of this one.

Hello,

I was wondering when this issue might be resolved?

[juliangilbey]

It seems that black is simply using its default value of 88.

To add to this, after updating to 5.2, it seems that autopep8 now also ignores the line length setting and goes for 88 characters :D
