fix for article.c:117:No such file or directory: bad Xref Xref: (site)

[Aaron Nabil <nabil@teleport.com>]

With multiple, disjoint servers, it possible that xrefRewriteCopy will
have gobbled up all of the Xref's, which will cause crosspost to
fail because it gets a Xref line that looks like Xref: host.com \n passed
to it.


Here is a fix...
