Hello, I would like to thank the authors, maintainers and all contributors for making such a cool project 😄

The reason why I was brought here is that recently we received a issue in the setuptools repository (pypa/setuptools#3072) that seems related to the fact that bazel does not support whitespaces in file names, and this might generate problems for people using rules_python.

As noted in of the issue's comment, even before the recent changes, setuptools already had files containing whitespaces.

My main objective here is just to give you guys a heads up, so you are aware about potential problems that might arise. (I understand that it might be a very complicated problem to solve and that it will take a long time...)

For the time being setuptools' lead developer have kindly provided a patch with a workaround, but it is difficult to guarantee that in the future other files containing whitespace in their names will not be added (specially via vendored dependencies).
