That is,
node.insert_after(nil, N, x)
is not a short-cut for inserting after N, but returns x as new head?
no, it returns n as head as well as x:
head, current = node.insert_after(nil,current,x)
boils down to
head = current
current = x
so:
head, current = node.insert_after(head,current,x)
becomes:
head = head or current or x
current = x
