Title: Fixed cloning a double-linked list.

Still need to determine if this is a systemic
issue and needs to be addressed higher in the
linked list hierarchy. For now, just
fixing the reported bug, with a note here
for other maintainers.

Review by @alex22 or @paulp. Let me know if you think I need to bump the clone method higher in the LL hierarchy.
