Re: Mixed L2R and R2L paragraphs and horizontal scroll

Because it's no more a window but a line property, IIUC.  When, after
scrolling the first line, you move `point' to show another portion of
the second line like this

      +---------+---------+-------------------+
      |$ijk     |abcdefgh$|abcdefghijk        |
      |KJIHGFED$|$HGFEDCBA|        KJIHGFEDCBA|
      |         |         |                   |
      +---------+---------+-------------------+

you get two different non-zero values of `window-hscroll'.  Or am I
missing something?

This would be needlessly inconvenient.  Hence, `window-hscroll' should
probably return the value for the line `window-point' is on.
