If you look at https://certbot.eff.org/docs/api/certbot.compat.filesystem.html, you'll notice many formatting errors which should be fixed.

That's the bare minimum which I think should be done, but I think we should also see what we can do to avoid these problems from happening in the future. Is there a way we could build the docs in CI and check for these problems?

The docs use certain coding style conventions that are no longer used in pandas (e.g., we adopt black's opinions in terms of line wrapping and quoting), for instance https://pandas.pydata.org/pandas-docs/stable/user_guide/merging.html. We should update the docs to match current style preferences.

blacken-docs is a useful tool that can help in doing _s
