The previous verison of this added on an  `&& options[:alternate_script] != false`  why is that not needed anymore?

You also remove my comment about the jruby bug we're working around, which I think is probably good to leave in so people know not to remove that apparently useless clause unless the jruby bug is confirmed fixed?

In general, I'm not sure why you wanted to rewrite the previous existing spec_covering_field method generally?
