[Red Gnus, prototype patch] nndoc support for preprint announcements (xxx.lanl.gov)

[Jan Vroonhof <vroonhof@math.ethz.ch>]

Hi Lars and all,

Naturally I split the daily preprint announcements I receive into
different mailgroups. Now it occured to me that they look a lot like
digests and so they would be a nice application for nndoc.

Just to see how difficult or easy it was I tried it and low and behold
it works! It is soooooo easy! (Thanks Lars!). I have included the
patch below.

Now this is a good application of the
kibozed-collection-of-nndoc-groups-of-all-messages-in-a-group
backend-to-come of Red Gnus if there ever was one.

Jan

P.S. I just noticed that the patch does't properly defvar
nndoc-type-alist, sorry. defvar is a pain if you are debugging.

Patch:
