These are uncontroversial and independent of a proposed LangRef edits (D44216). I tried to fix tests that would fold away: rL327004 rL327028 rL327030 rL327034 I'm not sure if the Reassociate tests are meaningless yet, but they probably will be as we add more folds, so if anyone has suggestions or wants to fix those, please do.
