Description

This just adds the note from #5415 to docs to explain that \ is not valid in ignore-paths per #5398 (comment) because it also currently is needed to support Windows path normalization. This will help avoid additional issues being created (like the one I created in #7089 and also someone else in #7094) to reduce the burden on pylint maintainers/developers.

Thank you for contributing to pylint ! Indeed we should have documented this better. I think the file you modified is autogenerated, could you search for the Python file with the same text and modify this one instead, please ?

@Pierre-Sassoulas it looks the the auto-upgrading tools rst doc removed my escape of the \ and now it doesn't render correctly in docs, rendering as:

Because '' represents the directory delimiter on Windows systems, it can't be used as an escape character.

What's the best way around that? Do I need to escape it again?

Does double escape work ? \\ (sometime even \\\\)
