There is an expectation in a before block on line 59 that enforces that `RSpec::Core::Random.srand` is called with the appropriate seed. This is the only spec for the `RSpec::Core::Runner.run` that specifically addresses setting a seed via the command line, though.

Would you prefer allowing the call in the before block with an explicit expectation in the `it` block here? In that case, I think it would be worth having at least one other spec that tests the default behavior, which is being handled via the pre-existing specs at this point.
