Patch #29 makes rn check the Xref system name against the site name mentioned
on the Relay-Version line, rather than against the site name that rn knows.
This fixes the bug once and for all.  It even lets you run rn on articles
installed by inews on a different machine, as in a local-area network with
news on a remote file system, without lying to rn as to what system you are
really on.  See net.sources.bugs.  Kudos to seismo!rick and sdcrdcf!jonab
for suggesting this approach.
