Subject: force-mode-line-update in post-command-hook renders scroll-conservatively worthless
Date: Mon, 15 Jul 2002 13:30:53 +0200 [thread overview]
Message-ID: <20020715132426.69FB.LEKTU@terra.es> (raw)
emacs -q --no-site-file
M-x set-variable scroll-conservatively 1000000
C-x C-n
<down>... ; Scrolls one line at a time
M-x ruler-mode
<down>... ; Cursor jumps to the middle of screen
; while scrolling the window
The reason is not ruler-mode, but the fact that it does:
(add-hook 'post-command-hook #'force-mode-line-update nil t)
AFAICS, adding `force-mode-line-update' (or in fact any function that
calls `set-buffer-modified-p') to post-command-hook makes
`scroll-conservatively' useless in all 21.X releases. It worked fine in
20.7.
