Apologies for not following this thread and perhaps misunderstanding at this point. If `transient-mark-mode' is off then there is no notion of an "active region". There is just the region. I doubt that someone who has `transient-mark-mode' off would ever want commands such as `flush-lines' and `sort-lines' to act on the region. And if they did, I expect they'd just narrow to it. Anything that works on "the active region" is something that makes sense only when `transient-mark-mode' is on (IMHO).
