# Detects double disable comments on one line. This is mostly to catch
# automatically generated comments that need to be regenerated.
#
# @example
# # bad
# def f # rubocop:disable Style/For # rubocop:disable Metrics/AbcSize
# end
#
# # good
# # rubocop:disable Metrics/AbcSize
# def f # rubocop:disable Style/For
# end
# # rubocop:enable Metrics/AbcSize
#
# # if both fit on one line
# def f # rubocop:disable Style/For, Metrics/AbcSize
# end
#
