 xdisp.c (IT_OVERFLOW_NEWLINE_INTO_FRINGE): For R2L lines,
 consider the left fringe, not the right one.
 (set_cursor_from_row): Don't reverse pos_before and pos_after for
 reversed glyph rows.  Set cursor.x to negative value when the
 cursor might be on the left fringe.
 (extend_face_to_end_of_line): Append the stretch glyph only if its
 width is positive.
 (notice_overwritten_cursor, draw_phys_cursor_glyph)
 (erase_phys_cursor): For reversed cursor_row, support cursor on
 the left fringe.
 w32term.c (w32_draw_window_cursor): For reversed glyph rows,
 draw cursor on the left fringe.
 xterm.c (x_draw_window_cursor): For reversed glyph rows, draw
 cursor on the left fringe.
 fringe.c (draw_fringe_bitmap): For reversed glyph rows, allow
 cursor on the left fringe.
 dispnew.c (update_text_area): Handle reversed desired rows when
 the cursor is on the left fringe.
 (set_window_cursor_after_update): Limit cursor's hpos by -1 from
 below, not by 0, for when the cursor is on the left fringe.

 xdisp.c (set_cursor_from_row): Compare candidate cursor
 positions only in rows whose buffer positions occlude point.
 (display_line): Fix computation of row->start and row->end for
 empty lines.
 dispnew.c (row_equal_p): Compare the reversed_p attributes as well.

 xdisp.c (handle_invisible_prop): If we are `reseat'ed, init the
 paragraph direction and set the `reversed_p' flag in the IT's
 glyph row.  Fix exit conditions of the loop that skips invisible
 text.  Update IT->prev_stop after skipping invisible text.  Check
 for additional overlays at IT->stop_charpos, not at start_pos.

Clean up the mess with setting the glyph row reversed_p flag.
 dispnew.c (prepare_desired_row): Preserve the reversed_p flag.

 bidi.c (bidi_cache_find): Use bidi_copy_it instead of copying
 the whole struct (which includes uninitialized parts).
 (bidi_init_it): Don't initialize bidi_it->paragraph_dir.

 xdisp.c (display_line): Remove misplaced setting of
 row->reversed_p flags.  Copy the reversed_p flag to the next glyph
 row.
 (next_element_from_buffer): Check bidi_it.paragraph_dir rather
 than level_stack[0].level.  Reset the reversed_p flag for non-R2L
 paragraphs.

(change_frame_size_1): newwidth == FRAME_COLS  (f) must
also be true before we can return early (bug #5339).

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.

An (unsuccessful) attempt to solve the issue with row->start and row->end.

 xdisp.c (set_iterator_to_next, reseat, reseat_1)
 (reseat_at_next_visible_line_start): Accept additional argument
 force_logical_p; all callers changed.  If force_logical_p is
 non-zero, force iteration in buffer's logical order even in bidi
 buffers.
 dispnew.c (direct_output_for_insert): Call set_iterator_to_next
 with additional argument zero.
 dispextern.h (set_iterator_to_next): Now accepts an additional
 argument.

Start of work on bidi Emacs 23/24.

 bidi.c (bidi_initialize): Fix initialization of bidi_type_table.

 xdisp.c (set_iterator_to_next): Fix position setting after call
 to bidi_get_next_char_visually.

 bidi.c: Include stdio.h unconditionally.  Fix and elaborate
 commentary.  Add Copyright blurb.

pre Emacs 22 emacs-bidi branch.
