You are right, of course. I knew about this 2-by-2 increase, but for 
some reason I convinced myself that that was related to an interference 
between the undo and the redo stack (don't ask).

Actually, it was just that I misread the documentation of allRelatives().

Fix pushed to master and stable.

Thanks, Scott!
