Join and split vehicles facing different ways without moving a car

Browse Source 
Joining took each card's cars in stored order and turned the lot by the
first card's flag, so a turned card came out reversed; splitting gave every
car the unit's flag. Both now go by the running order, and the coupler sides
by each car's own facing, which is what the export writes.
