Thanks a lot for taking the time to create this PR, it's much appreciated :)

Why change the line length to 80 though? The default 88 looked fine to me.

Why change the line length to 80 though?

i don't know. this branch was stale for a while. changed it back to 88 now. aa2c49f

[vxgmichel]

The back and forth between 80 and 88 max length caused more changes than necessary.

I pushed those changes and migrated the rest of setup.cfg in PR #103.

Thanks for your valuable help :)

that's unexpected, because I thought black was so uncompromising, that the result would be reproducible even when switching between different lengths. but I don't mind ;)
