Auto-fail a spec with no assertions

[Dan Bernier]

Could a spec with no expectations automatically pend, or fail? possibly controlled via a flag?

    it 'should have muffins'

      baker.has_muffins?    # <- a quick scan makes this look right

      expect(baker.has_muffins?).to be_true  # <- but you need this

    end

    $ rspec   # The empty spec passes

    $ rspec --fail-empty-specs   # The empty spec fails

    $ rspec --pend-empty-specs  # The empty spec pends

In an ideal world, this would be unneeded. But when you work on a large code base, and you're interrupted, it's pretty easy to make this mistake.

This has been discussed several times before:

https://github.com/rspec/rspec-core/issues/759

https://github.com/rspec/rspec-core/issues/591

https://github.com/rspec/rspec-core/issues/404

I just reopened #759 as I'm more onboard with adding this than before.  Let's continue discussion there.

BTW, here's a way you can get this now:
