+
+ * xdisp.c (next_element_from_buffer): Improve commentary for when
+ the iterator is before prev_stop.
+ (init_iterator): Initialize bidi_p from the default value of
+ bidi-display-reordering, not from buffer-local value. Use the
+ buffer-local value only if initializing for buffer iteration.
+ (handle_invisible_prop): Support invisible properties on strings
+ that are being bidi-reordered.
+ (reseat_to_string): Enable bidi-related code.
+ (set_iterator_to_next): Support bidi reordering of C strings and
+ Lisp strings.
+ (next_element_from_string): Support bidi reordering of Lisp
+ strings.
+ (handle_stop_backwards): Support Lisp strings as well.
+ (display_mode_line, display_mode_element): Temporarily force L2R
+ paragraph direction.
+ (display_string): Support display of R2L glyph rows. Use
+ IT_STRING_CHARPOS when displaying from a Lisp string.

+ strings.
+ (init_iterator, reseat_1, reseat_to_string): Initialize the
+ string.bufpos member to 0 (zero, for compatibility with IT_CHARPOS

+ (display_prop_intangible_p): Reimplement to call
+ handle_display_spec instead of single_display_spec_intangible_p.

+ FRAME_WINDOW_P. Call handle_display_spec to determine whether the

+ (handle_single_display_spec): Accept 2 additional arguments BUFPOS

+ the display property, but just return a value indicating whether
+ the display property will replace the characters it covers.
+ (Fcurrent_bidi_paragraph_direction): Initialize the nchars and
+ frame_window_p members of struct bidi_it.
+
+ * bidi.c (bidi_fetch_char): Accept additional argument

+ * bidi.c (bidi_resolve_explicit_1): Use ZV for disp_pos.
+ (bidi_fetch_char): Implement support for runs of characters
+ covered by display strings.
+
+ * bidi.c (bidi_fetch_char): Accept also character position

+ (bidi_resolve_explicit, bidi_resolve_weak)
+ (bidi_level_of_next_char, bidi_move_to_visually_next): Abort if
+ bidi_it->nchars is non-positive.
+ (bidi_level_of_next_char): Don't try to lookup the cache for the
+ next/previous character if nothing is cached there yet, or if we
+ were just reseat()'ed to a new position.
+ (bidi_paragraph_init, bidi_resolve_explicit_1)
+ (bidi_level_of_next_char): Fix arguments in the calls to
+ bidi_fetch_char.

+ (LRE_CHAR, RLE_CHAR, PDF_CHAR, LRO_CHAR, RLO_CHAR): Remove macro
+ definitions.

+ instead of using explicit *_CHAR codes.
+ (bidi_resolve_explicit, bidi_resolve_weak): Use

+ process will be redirected to a file specified with `:file'.
+ Don't try to re-open tempfile in that case, and set fd[0] to -1 as
+ cue to call_process_cleanup not to close that handle.
