Issue 5754: tweak shelve doc wording to make it clearer that even when
writeback=True values are written to the backing store when assigned to
the shelf. Add test to confirm that this happens. Doc patch and added
test by Robert Lehmann. I also fixed the cross references to the sync
and close methods.
