Fix pretty-printing nested empty lists and add test suite

The earlier "test" was just hitting the code without actually checking the
output.  This new suite is a set of pretty-printed documents which serd must
reproduce from a model exactly to pass.  This should make it easy to add cases
in the future, since each case is just a document, as it should look.
