Lists are paged, yet sample code doesn't show this

[pmorriss]

I was tracing a bug in my own code and I discovered that when I get a list of, say, unsubscribed subscribers using the code in samples/lists.py line 27
for cm in list.unsubscribed().Results:
that it only returns a certain number of results. If I want the full list of unsubscribed people then I have to use a paging method, as is used, for example, in clients.py.

Could the sample code for lists show a paged method?
