great job, please take a look at the string join

[asottile]

hrmmm, seem to be hitting pre-commit/pre-commit#835 (which itself is an intersection of pip / virtualenv / black / windows)

[asottile]

I think this might magically fix itself when virtualenv makes a release. So I'm going to wait on that :)

[RonnyPfannschmidt]

great work :)

@RonnyPfannschmidt oh uh, this breaks the linting env on windows -- I wasn't quite ready to merge it yet 😆

couple of options:

• temporarily disable linting on windows (should be fixed by the end of the week once virtualenv releases if my hunch is right)
• upgrade the linting env to python3.7 (should use UTF-8 mode I think?)
• revert-revert and then I can re-apply later

[RonnyPfannschmidt]

@asottile oh, my bad - lets disable linting on windows and create a followup issue for after virtualenv releases

[asottile]

no problem! I made #4094 and #4095 to handle this
