Killing text from article buffers goes weird

[Tassilo Horn <tassilo@member.fsf.org>]

Hi all,

lately, I have pretty hard times killing regions from article buffers
and yanking them in another buffer.  What I've killed doesn't match what
comes out of the yank.

Let's use my message <87ipww6pzc.fsf@member.fsf.org> on this list as an
example.  In the article buffer, I marked the following region:

--8<---------------cut here---------------start------------->8---
in my ~/.gnus.el to let Gnus regularily fetch news and mail.
Unfortunately, sometimes the fetching process seems to hang.  In the
echo area, I can read something like
--8<---------------cut here---------------end--------------->8---

Now I yank it here, and get this!

--8<---------------cut here---------------start------------->8---
Message-ID: <87ipww6pzc.fsf@member.fsf.org>
User-Agent: Gnus/5.110011 (No Gnus v0.11) Emacs/24.0.50 (gnu/linux)

Hi,

I have this

  (require 'gnus-demon)
  (gnus-demon-add-handler 'gnus-demon-scan-news 15 5)
--8<---------------cut here---------------end--------------->8---

Ok, I kill that region again, C-y here (same wrong text as above), then
M-y, and then I finally have the correct text.

--8<---------------cut here---------------start------------->8---
in my ~/.gnus.el to let Gnus regularily fetch news and mail.
Unfortunately, sometimes the fetching process seems to hang.  In the
echo area, I can read something like
--8<---------------cut here---------------end--------------->8---

Another madness: The article has the folllowing displayed headers
(again, I have to kill, C-y, M-y to get them correctly yanked; after the
C-y only the headers till the Date header (including) are there):

--8<---------------cut here---------------start------------->8---

--8<---------------cut here---------------end--------------->8---

Now I set point to the start of the Message-ID-header line, go down one
line, so that the Message-ID line is in the active region, and when the
funky Date header gets updated after one second, the start of the region
expands to the beginning of the Date header line!

When looking at my examples, I'm pretty sure it has something to do with
that new Date header display (which I like!).  All the wrong text seems
to be "bounded" to the Date header: either the wrong regien ends there
(including), or it starts there (excluding).

Bye,
