I'm happy to say that this patch solved our off-by-one problem quite
nicely. And I'm honestly happy to just have a working Z39.50 server,
with the ability to scope searches by org_unit and surface holdings in
a way that makes VDX happy, without worrying too much about whether
the cause of the off-by-one lies in the Evergreen code or the
Simple2ZOOM code.

Thanks a ton, Warren! We should update the SRU/Z39.50 section of the
wiki to reflect the status of the server, it has come a long way in
the last month!
