This is in response to @myronmarston comment about adding standard checks to the code (see: https://github.com/rspec/rspec-core/pull/1461#issuecomment-39118001).

It's not really global for cucumber specs. This file is added before each feature when it is setup. It is easy to allow the one liner should syntax by tagging the spec with `@oneliner-should`; rspec-expectations already does this. We can add more tags when necessary too.
