Subject: 23.0.91; Gnus: gnus-summary-toggle-truncation needs manual update
Date: Sun, 31 May 2009 19:51:05 +0300

In Gnus summary buffer there is command gnus-summary-toggle-truncation
(C-t). It seems to do pretty much the same as toggle-truncate-lines
command, except that the former does not update the buffer after toggle.

Try this:

 1. Enter Gnus summary buffer

 2. Make the window so narrow that the lines don't fit horizontally in
    the window.

 3. Press C-t

 4. Nothing happens until you update the window, with C-l, for example.

This used to work with my Emacs 22.2.

retitle 3436 (redraw-display) does not always redraw display
thanks

It seems that function gnus-summary-toggle-truncation hasn't been
changed in more than ten years so I guess that function can't be causing
the problem. The problem is somewhere else. Let us have a more general
title for the bug.

I'm unable to see this problem in Emacs 24.  Can you still reproduce the
bug in a current Emacs?

I'm using 23.2 (Debian) and don't see the problem in it. I guess this is
DONE.
