I think you got it wrong here. Newspaper article are written a whole
paragraph without new lines on a wide screen and then reflowed to
the column width. You can do it with any word processor, and change
the width when you print and get the same behavior.

You keep saying "when there's a newline" and "use fill-paragraph"
because of your technical constraint (explained in another email).

I propose the following: use a virtual "right-margin-goal-column" (a
real one if given, and if not it is the screen width), do a virtual
`fill-paragraph' on the line, and do the bidi processing on the
result, BUT without inserting any real new-lines.

It has the shortcoming of not going exactly up to right edge (or left
edge for R2L paragraph), but it will have the benefit of not breaking
words and allowing normal reading for long line with embedding text of
the opposite direction.

It does not solve or even relate to the scrolling strategy.

Ehud.
