Article Editing - header gets corrupted

Article Editing - header gets corrupted

[Holger Sparr]

Hi,

sometimes I want to edit an article in one of my nnfolder groups.  I am
used to do this by pressing `e' in the summary buffer.

After finishing with `C-c C-c' and redisplaying the article with `g',
articles with longer From-lines disappear.

Examing the nnfolder file suggests that the From-line gets filled like
this (`auto-fill-mode' is turned on via the `text-mode-hook'):

,----
| From longer.name@long.host Mon Jan 28
|      11:15:16 2002
`----

When I edit the file directly to:
,----
| From longer.name@long.host Mon Jan 28 11:15:16 2002
`----
the article reappears.

Is this a bug? (Maybe, it has been reported already.)

Holger

PS
When I edit the raw article (ARG is 1) everything works as expected.

The bug would be that you shouldn't do filling in the headers, or at least
not in the 'From ' envelope header.  As far as I can remember, nnfolder
uses the From envelope header to find where articles start, and it
requires that the line follows a certain format.

yes, I reported this in August 2001 [1]. Recently, Lars made some
changes in gnus-sum.el [2] in order to fix it, but finally he was
unable to reproduce the bug [3].

I didn't try this before. Maybe this helps to locate & fix the bug.

No, the problem also appears without any auto-filling. I can reproduce
it with a minimal ~/.emacs, ~/.gnus and `emacs --no-site-file'. (See
the thread "gnus-summary-edit-article and wrapped From-line" starting
with <v9vgj4pa4z.fsf@marauder.physik.uni-ulm.de>.)

Editing the article should retain this format, but it doesn't. The
problem seems to be related to the call of rfc2047-fold-region in
rfc2047.el (see <v98zbg9x89.fsf@marauder.physik.uni-ulm.de>).

Bye, Reiner.
