Globally looks for .rubocop_todo.yml regardless of configuration

[jdickey]

Given this Guard definition in my Guardfile:

guard :rubocop do
  watch(%r{^lib/crypt_ident/.*?[^/]+\.rb$})
end

I expect only files in or below the lib/crypt_ident directory to be inspected. Yet it goes off into my tmp/gemset directory as well. Why? How can this be fixed?
