for those who want the up arrow to scroll up in acme 
and 8½, here are the appropriate diffs.
the line numbers might not match the cd exactly.
both code fragments come after a very similar one
with the string "VIEW" in the comment.  in both cases
its the only occurrence of VIEW in the entire source.
