nnmairix - new version

[David <de_bb@arcor.de>]

This was first posted in the wrong group (gnus.user instead of ding). My
first try at posting the diff to ding via Gmane seems to have failed, so
I try again. If it the first post shows up eventually, sorry for the
double post and all the noise...

There's a new version of nnmairix; the diff against the current CVS can
be found here:

http://m61s02.vlinux.de/nnmairix_v0.6.diff.gz

I've also converted the docs at the EmacsWiki into texinfo for inclusion
in the Gnus manual.

I've no real idea where this section would fit best. Maybe there should
be a new section for searching/indexing mail and put it there, together
with the documentation for nnir?

The diff for the new version got pretty big, sorry for that. Almost
everything deals with a new feature, allowing to propagate marks from
articles in nnmairix groups to the original article, which was way more
delicate than I previously thought and couldn't really be split in
smaller parts.

This "marks propagation" option can be activated on a per-group basis
(it's deactivated by default). It allows to use nnmairix more
efficiently as an alternative to mail splitting, which was actually my
prime motivation when I started with this, since my fancy-split-rules
started to get out of hand...

Unfortunately, the new marks propagation feature requires a patched
mairix binary. People who are not interested in marks propagation won't
have to patch, but it also fixes some annoyances regarding changing
maildir flags, so it might be useful anyway.

More details can be found in the updated docs at the EmacsWiki:

For those who don't use CVS, the new source is also at

http://www.emacswiki.org/cgi-bin/emacs/nnmairix.el

Other new features: 

* Keep messages in nnmairix always read or unread.

* New option to enable/disable fast entering of nnmairix groups.

* Recreate back end folder in case of wrong article counts.

* More and better use of the registry for searching original articles.
