The correct inews patch for 2.10.1 systems can be found in <1357@sdcrdcf.UUCP>
(bug #5) in either net.new.b or net.sources.bugs.  It's actually simpler than
the bogus 2.10.1 inews.c patch, since inews no longer has to carefully
cross-match the Xref line with the Newsgroups line.  What happened was I
had modified the 2.10.1 inews, but forgot to run the diff before posting
the kit, so I got a old version of the patch into the kit.  Sorry 'bout that.

The reason the Xref format changed was to support newsgroup aliasing of
2.10.2.  Newsgroup aliasing means that the list of newsgroups actually
posted to on a machine may bear little relation to the list of newsgroups
on the Newsgroups line.  Originally I wanted to save a bit of disk storage
by running the Xref line in parallel with the Newsgroups line, but that
was not to be.  I console myself with the fact that the new Xref format
simplifies both the inews patch and rn, and is more robust to boot.

Happy Hacking,
Larry Wall
