-If you're using Flake8, you can bump `max-line-length` to 88 and forget about it.
-Alternatively, use [Bugbear](https://github.com/PyCQA/flake8-bugbear)'s B950 warning
-instead of E501 and keep the max line length at 80 which you are probably already using.
-You'd do it like this:
+If you're using Flake8, you can bump `max-line-length` to 88 and mostly forget about it.
+However, it's better if you use [Bugbear](https://github.com/PyCQA/flake8-bugbear)'s
+B950 warning instead of E501, and bump the max line length to 88 (or the `--line-length`
+you used for black), which will align more with black's _"try to respect
+`--line-length`, but don't become crazy if you can't"_. You'd do it like this:
```ini
[flake8]
-max-line-length = 80
+max-line-length = 88
...
select = C,E,F,W,B,B950
extend-ignore = E203, E501
```
-You'll find _Black_'s own .flake8 config file is configured like this. Explanation of
-why E203 is disabled can be found further in this documentation. And if you're curious
-about the reasoning behind B950,

[Bugbear's documentation](https://github.com/PyCQA/flake8-bugbear#opinionated-warnings)
explains it. The tl;dr is "it's like highway speed limits, we won't bother you if you
overdo it by a few km/h".
How do you make it stop? Just delete that trailing comma and _Black_ will collapse your
collection into one line if it fits.
+If you must, you can recover the behaviour of early versions of Black with the option
+`--skip-magic-trailing-comma` / `-C`.

_Black_ normalizes string quotes as well as string prefixes, making them lowercase. One
