Prevent spec from issuing confusing output.
Prevent spec from issuing confusing output.

On ruby 2.0.0, `rspec --seed 1325` would issue confusing
output where the end-of-run summary is printed twice.
See the following example output below.

This spec was the culprit. It's not actually concerned
with running the command line so we might as well stub it out.

Run options:
  include {:focus=>true}
  exclude {:ruby=>#<Proc:./spec/spec_helper.rb:152>}

All examples were filtered out; ignoring {:focus=>true}
.....No examples found.

Deprecation Warnings:

Using `stub` from the old `:should` syntax without explicitly enabling the syntax is deprecated. Use the new `:expect` syntax or explicitly enable `:should` instead. Called from /Users/myron/code/rspec-dev/repos/rspec-core/spec/rspec/core/runner_spec.rb:57:in `block (3 levels) in <module:Core>'.
