rubocop-auto-gen-config-missing-exclude-demo

This repository demonstrates a bug with

% rubocop --auto-gen-config

It correctly detects that the majority of files adhere to the snake_case method naming convention.

# good/*.rb
def good
end

However, while this file violates the convention

# bad/zero.rb
def Bad
end

no Exclude section is added to .rubocop_todo.yml, whereas it is for other cops.

 # This configuration was generated by
 # `rubocop --auto-gen-config`
 # on 2023-12-27 00:45:53 UTC using RuboCop version 1.59.0.
 # The point is for the user to remove these configuration records
 # one by one as the offenses are removed from the code base.
 # Note that changes in the inspected code, or installation of new
 # versions of RuboCop, may require this file to be generated again.
 
 # Offense count: 1

This leaves the repository with offenses, despite having just run --auto-gen-config.
