scroll-margin bugs

[Jesper Nordenberg]

Some more info in the scroll-margin bugs. Here's how to reproduce the 
hanging Emacs bug:

1. Start a clean Emacs: emacs -q --no-site-file
2. Set scroll-margin to 5.
3. Set scroll-conservatively to 1000.
4. Scroll a big buffer so that the last line is just visible.
5. Press page down.
6. Emacs freezes.

Here's how to make scroll-margin not work correctly when scrolling down:

1. Start a clean Emacs: emacs -q --no-site-file
2. Set scroll-margin to 5.
3. Set global-hl-line-mode to on (using customization).
4. The buffer only scrolls down when the cursor moves out of screen.

I'm using Emacs 21.1.1 on Windows 2000.
