Btw, please note that some residual problem remains: after the patch,
if a buffer begins with 2 newlines and an RTL letter, the first screen
line is rendered right-to-left, which is wrong.  You can see that it's
wrong if you insert more newlines at BOB: then only the single empty
line immediately before the RTL letter is rendered right-to-left.

Of course, this is better than the original problem.
