Rémi, thanks for the review.  I've added you as a reviewer.

I agree.  Although relying on such implementation details is a bad idea,
and implementations are very likely to differ, and the existing LinkedList
is a hodge-podge of differing styles of methods calling other public
methods, we should strive to maintain this kind of compatibility if
the price is not too high.

Also, I did some cosmetic touchups, and commented out the asserts.

Webrev regenerated.
