Package: emacs
Version: 23.0.60
Severity: normal

After setting this in .emacs:

(setq scroll-preserve-screen-position 'always
      scroll-conservatively           most-positive-fixnum ;; any large number
      scroll-step                     0)

scroll-down causes recentering. This is a regression.

The bug was apparently introduced by the following change:

2008-08-06  Chong Yidong  <address@hidden>

        * xdisp.c (try_scrolling): Use iterator to find the scroll margin,
        instead of window-end which does the wrong thing at eob.
        (try_cursor_movement): Minor optimization.
        (redisplay_window): If scroll margin is defined, don't assume
        window doesn't need scrolling.

Fixed by Chong Yidong with this change:


2008-10-27  Chong Yidong  <cyd@stupidchicken.com>

        * xdisp.c (try_scrolling): When computing the distance from the
        scroll margin to PT, try moving some distance past the window
        bottom before giving up.
