I've patched back-meta in HEAD: if you add the "client-pr" directive, it
will perform the client-side of RFC 2696 paged results (either always,
with the specified page size, or in response to unsolicited paged results
response).  This will be totally transparent to the actual client, so the
client no longer needs to perform paged results itself.

Please test and report.  Thanks, p.
