* Make_HandleUse --

/* Called by Make_Run and SuffApplyTransform on the downward pass to handle

* A .USE node is much like an explicit transformation rule, except
* its commands are always added to the target node, even if the
* target already has commands.
* A .USE node is much like an explicit transformation rule, except its

* Input:
* cgn The .USE node
* pgn The target of the .USE node

* Results:
* none
*
* Side Effects:
* Children and commands may be added to the parent and the parent's
* type may be changed.
