Description
When I created a list of paths separated by colon (like $PATH envvar) including Rails.root, the Rails/FilePath cop warns to use Rails.root.join. But it's not appropriate in this case.
Expected behavior
No warning is emitted.
Actual behavior
$ bundle exec rubocop --require rubocop-rails
Inspecting 2 files
.C
Offenses:
test.rb:3:8: C: Rails/FilePath: Prefer Rails.root.join('path/to').
PATH = "#{Rails.root}:/path/to/directory"
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
2 files inspected, 1 offense detected
