I've finally determined that item delimiters come after the item.
The last item of a list does not have to have a delimiter --it is
optional if no more characters in the list. To keep out of trouble,
and make cleanup of the last delimiter unnecessary, I always keep the
trailing delimiter in my lists. Unfortunately, it is always left off
when a chunk is returned --even if the last item was empty, meaning
you lose one item (though an empty one). You can fix this by always
appending a delimiter to a returned chunk. However, in the case
where you ask for more items than the list has, it will keep the
trailing delimiter. You must be vigilant to keep the number of items
correct in a sparse regular array. It would take a whole tutorial
just to explain the proper care and feeding of delimiters.

Any comment ?
