[Benadir] redisplay glitches

I'm not sure if this is a recent problem, or if cosmetic problems need be fixed before the final release. But, I'm able to produce redisplay "turds" in b50 by doing the following: (1) xrdb < /dev/null (2) xemacs -vanilla (3) \C-h a horizontal (4) \C-x \C-f /usr/local/bin # or any directory that gives > page of output (5) \C-x \C-b *Hyper # or any buffer with a horizontal scrollbar (6) \C-x \C-b *scratch* => the last dired line is still visible in the *scratch* buffer. -- -mb-
