Interesting... However, before I make any  change to the code I need some
sort  of formal  assurance  that these  tags are  indeed  present in  all
(conformant)  usenet messages,  and are  not part  of any  current RFC822
extension.  In fact,  I  am  pretty sure  I  have  seen messages  without
'Supersedes:' or  'Archive-Name:' (I  understand you were  addressing the
particular problems  of FAQ, but I'd  like a solution that  works for all
usenet messages, rather than just FAQ files).
