Subject: inconsistent behavior with scroll-margin and scroll-conservatively
Date: Tue, 04 Mar 2008 12:03:14 -0800

I have scroll-margin set to 5 and scroll-conservatively set to 1000. The
behavior I want is while arrowing up or down, the screen scrolls by 1
line, starting 5 rows from the top or bottom. This works fine if
arrowing up while the bottom of the buffer is not on screen, but if
arrowing down, then the cursor goes all the way to the last row and
then scrolls the screen by 5 lines. It also appears to do this even
while going up if the end of the buffer is visible.

Thanks -- Andy
