You know, now I'm embarrassed, because I really should have come up with this
myself. :-P
Actually, I think I did, but I was concerned that the returned result wouldn't
actually be identical to the original, inasmuch as e.g. inserting the nodes one
by one might cause everything to be in a different order to the original. So I
didn't have the confidence to try it out.
Of course, I could always test these things ...
Thanks very much for the suggestion!
