exclude_files_in is always overwritten when passed as a parameter to RuleList.

[laurynmm]

In zulint/custom_rules.py, theoretically exclude_files_in can be passed as a parameter when creating a RuleList, but it's always set as "\\" no matter what string is passed as a parameter. See code block below.

I'm not sure what the intention was as exclude_files_in is not listed in the documentation comment "Rule help" as a way to exclude files. There's only one current instance of it's use in zulip/zulip, here.

class RuleList:
    """Defines and runs custom linting rules for the specified language."""

    def __init__(
        self,
        langs: Sequence[str],
        rules: Sequence[Rule],
        exclude_files_in: Optional[str] = None,
    ) -> None:
        self.langs = langs
        self.rules = rules
        # Exclude the files in this folder from rules
        self.exclude_files_in = "\\"
        self.verbose = False
