when i select subtrees and m-s-right, they demote, and then i have no further use for the active region, and have to press c-g.  is it possible to turn off the persistence of the region so that it follows earlier behavior and disappears once done?

i have not found a use for the new behavior yet, and would like to revert if there is a var controlling it.  thanks.  i realize it was a deliberate decision and must be a very useful one to others.  :)  ^G feels like a "get out of wrongness" fallback command, not an "expected thing you to to turn off the region" command.  but that is just me.
