Sure, will do. FWIW – "Fix the copyrights to a single year rather than a range" feels artificial.

It's not; it ensures that the range doesn't need to be updated every year.

??? The range only needs to be updated in years when the tests are modified, not when the calendar advances. Anyway. I will change the tests to conform with this peculiar requirement.

The linter is now happy and I've attempted to resolve all comments.

Thanks for the review @anba. This is very helpful.

I'd prefer not to make this PR any bigger so let's not fix the missing coverage here, instead please consider opening an issue with a testing plan.

The helpful feedback from @anba have been applied.

As per discussion with @gibson042, we'll break this up into multiple PRs based on the test plan, when available.

The changes of this PR have now been incorporated into scoped PRs linked to from the test plan.
