On some sites, with the upgrade of news to 2.10.3 or 2.11, rn's Xref 
facility broke.  The culperate appears to be a change in the Xref format.
I don't remember what the old Xref format was, but the new format doesn't have
any commas.  Rn assumed that the Xref must have a comma and if not, it wasn't
an Xref line.  Note this only applies if rn is compiled with DBM defined.  

There may be similar problems in the non-DBM version but I didn't look at
that code closely enough to tell other than it assumes that it has tabs,
which the new Xref line doesn't (no patch for that provided [sorry]).
