Massimiliano Culpo 90756d0428 Refactor UI logic out of Environment.concretize (#12213) ... Environment.concretize returns newly-concretized specs rather than printing them; as a result, the _display argument is removed from Environment.concretize (originally only used to avoid printing specs during unit testing). Command logic which invokes Environment.concretize prints these explicitly.		2019-08-02 17:27:51 -07:00
