I don't think so. The patch just avoids the use of negative offsets but
it doesn't deal with the excessive line length afaics. If you read
my explanation of the editor problem, you'll see that the unpleasent
visual effect is due to fact that when using certain ncurses routines
to write lines longer then COLS you'll get the excess columns on the next
line.
