[code-quality] Need help: pylintrc breaks black_list from plugins

Hi folks, according to this bug report: https://github.com/PyCQA/pylint-django/issues/167#issuecomment-401304800 when there is a .pylintrc file with an ignore line inside of it it this overrides the black_list options configured by plugins. In the case of pylint_django we would like to ignore some directories (like migrations) and this breaks. In pylint_django we have: def register(linter): linter.config.black_list += ('migrations', 'south_migrations') and from what I can tell after this is set something calls OptionsProviderMixIn.set_option and overrides it afterwards. Is that a desired behavior or a bug? If this is a bug where should I look if I want to contribute a patch ? Regards, Alex
