Appease rubocop

[BenGitsCode]

We may need to ignore some i.e. spec/equine_spec.rb:1:1: W: Unnecessary disabling of Metrics/BlockLength. but the frozen string literal comments should definitely be fixed.

spec/equine_spec.rb:1:1: W: Unnecessary disabling of Metrics/BlockLength. Should be handled by the .rubocop.yml, no?

[BenGitsCode]

I wasn't sure about that one.

Reading this https://github.com/bbatsov/rubocop/issues/3664#issuecomment-275860483, it sounds like it depends on which version. If we're planning to continue at 0.46.0 we should be to include something like this in the .rubocop.yml

Metrics/BlockLength:
  Exclude:
    - "**/*_spec.rb"

[raq929]

Yes. The disabling of Metrics/Blocklength in a comment should be removed, as it is now covered by .rubocop.yml.
