The simplifying "cleanup" fix e5f3b815f4d introduced a subtle bug: it now allows duplicate entries to appear on vundo--timestamps, which is an alist (where only "first match" counts) but is also a time-sorted list, for which duplicates do matter. In some situations this defeats previous/next saved node navigation, since the current and target node are identical.
