    Eli Zaretskii authored
     src/xdisp.c (move_it_in_display_line_to): Record prev_method and
     prev_pos immediately before the call to set_iterator_to_next.
     Fixes cursor motion in bidi-reordered lines with stretch glyphs
     and strings displayed in margins.  (Bug#8133)  (Bug#8867)
     Return MOVE_POS_MATCH_OR_ZV only if iterator position is past
     TO_CHARPOS.
     (pos_visible_p): Support positions in bidi-reordered lines.  Save
     and restore bidi cache.
     (move_it_in_display_line_to): If iterator ended up at
     EOL, but we never saw any buffer positions smaller than
     to_charpos, return MOVE_POS_MATCH_OR_ZV.  Fixes vertical cursor
     motion in bidi-reordered lines.
