Undo changes from 2009-09-11. Set row->end and row->start in xdisp.c:display_line. dispnew.c (direct_output_for_insert): Give up if we are reordering bidirectional text. dispextern.h (IT_STACK_SIZE): Enlarge to 5. xdisp.c (display_line): Set row->end and it->start for the next row to the next character in logical order. If we are reordering bidi text, push and pop the iterator before and after momentarily iterating in logical order.

|
(reseat_at_next_visible_line_start): Accept additional argument
