Next attempt - sorry for the delay, missed the update emails to this bug.

Not sure whether removals count towards the 15 line limit but copyright 
assignment should be through now - could you please confirm, when you're 
at it?

Thanks

Jens

Subject: [PATCH] Remove obsolete information on archiving mail

The Gnus manual still references long-removed external marks in
section "Archiving Mails".  Without external marks that section is
almost pointless, so remove it completely (Bug#63497).
* doc/misc/gnus.texi (Top):
(Browsing the Web): Remove references to section.
(Archiving Mail): Remove section.

-Some of the back ends, notably @code{nnml}, @code{nnfolder}, and

-To archive an entire @code{nnml}, @code{nnfolder}, or @code{nnmaildir}
