Is there a charset that uses right-left and multibyte?
I know some codes in MULTI_BYTE have rlflag settings.
It could be removed. But I don't know about it. You can clean up the code.

This is yet another patch. And I tune up some code for performance and
safe bound check. (removed a IsTrailByte() call)

I have attached a new patch, to be applied to the original screen.c,
which includes both of Chong-Dae Park's patches. I have also made the
new fix for bold fonts only take place in the GUI, not in xterm as
well, as per Bram's request.
I also renamed a few things:
update_this --> redraw_this
update_next --> redraw_next
is_needs_update --> needs_redraw
I think "redraw" is a more specific description of the action required
than "update", and "needs_redraw" just reads better. I still think
that function could do with a longer more descriptive name though.
"needs_redraw" is a very general description, but I guess it'll do.

place that the flag is tested for (other than next time around the
loop, which won't be reached in this case), is for the new bold trick,
in which case it might decide to redraw the current character
unnecessarily. But if this only happens when force is set, then it'll
get redrawn anyway, so no harm done.
