Bug: Scroll-margin

Bug: Scroll-margin

[Wilmar Igl]

Dear Emacs developers,

I'm currently using
GNU Emacs 22.0.92.1 (i386-mingw-nt5.1.2600) of 2006-12-29 on 
LENNART-69DE564 (W32 package, patched) under MS Windows XP
and I'd like to point out that the options

(setq-default scroll-margin 5) ;; this does not work
(setq-default scroll-step 1)
(setq-default scroll-conservatively 1000)
(setq-default scroll-preserve-screen-position 't)

don't work properly, to achieve _smooth_ scrolling. When I scroll up 
within a buffer everything works as expected, only when I scroll down 
the cursor often touches the window border and only occasionally behaves 
as expected. In a previous Emacs version (22.0.5.xxx) the same scrolling 
  problems (like now at the bottom border) appeared in both directions 
(up and down), so maybe the bug is already partially fixed.

After googling I've found a page (sorry, couldn't find the link again) 
where somebody else tracked that problem back to differences between the 
  displayed text and the actually safed text (or something like that).

As I think smooth scrolling is very much desirable and that the 
_recentering of the cursor_ after leaving the window is _highly 
irritating_ I suggest to implement _soft scrolling_ as the _default_ 
option in Emacs 22.1.

Thank you very much for your work and looking forward to the official 
release of Emacs 22.1

Yours,

Wilmar Igl
