Or just use NewsWWW, because nntp://<HOSTNAME>/<Message-ID> is valid.
Going to think about it while I eat and do other things, but
will very likely merge it to master, soon.

Subject: [PATCH] newswww: add /$MESSAGE_ID global redirector endpoint
This is the fallback for the normal WWW endpoint.
Adding this to the top-level seems to be alright, since lynx and
w3m both understand nntp://<HOSTNAME>/<Message-ID> anyways.
If newsgroup and inbox names conflict, then consider it the
fault of the original sender.
Since NewsWWW is intended to support buggy linkifiers in mail clients,
they can interpret nntp:// URLs as http://<HOSTNAME>/<Message-ID>
Inbox ordering from the config file is preserved since
commit cfa8ff7c256e20f3240aed5f98d155c019788e3b
("config: each_inbox iteration preserves config order"),
so admins can rely on that to configure how scanning
works.
