Oops, you're right. I assumed I was changing __copy__ only. Pull
Given that behaviour is documented it really ought to be tested. I'll add one.

Agreed, but for now the .copy() method's default shouldn't change. I
think the scikit-learn usecase I described is a good reason why the
copy protocol methods should maintain data ordering, though.
