+
+       These changes are to detect incorrect composition sequence without
+       looking ahead the source.
+
+       * coding.h: Include "composite.h".
+       (enum compisition_state): New enum.
+       (struct compisition_status): New struct.
+       (struct iso_2022_spec): New member cmp_status.
+       (struct emacs_mule_spec): New struct.
+       (struct coding_system): New members ctext_extended_segment_len and
+       embedded_utf_8.  Change the union member
+       spec.emacs_mule_full_support to spec.emacs_mule.
+
+       * coding.c (CODING_ISO_CMP_STATUS): New macro.
+       (CODING_ISO_EXTSEGMENT_LEN, CODING_ISO_EMBEDDED_UTF_8): New macros.
+       (MAX_ANNOTATION_LENGTH): Defined to 5.
+       (ADD_COMPOSITION_DATA): New arg nbytes.
+       (emacs_mule_char): New arg cmp_status.
+       (DECODE_EMACS_MULE_COMPOSITION_CHAR): Delete it.
+       (DECODE_EMACS_MULE_COMPOSITION_RULE_20): New arg c.
+       (DECODE_EMACS_MULE_COMPOSITION_RULE_21): New arg c.
+       (DECODE_EMACS_MULE_21_COMPOSITION): Delete the arg c.
+       (DECODE_EMACS_MULE_20_RELATIVE_COMPOSITION): Likewise.
+       (DECODE_EMACS_MULE_20_RULEBASE_COMPOSITION): Likewise.
+       (DECODE_EMACS_MULE_COMPOSITION_START): New macro.
+       (EMACS_MULE_COMPOSITION_END): New macro.
+       (emacs_mule_finish_composition): New function.
+       (EMACS_MULE_MAYBE_FINISH_COMPOSITION): New macro.
+       (decode_coding_emacs_mule): Avoid long looking ahead while
+       handling composition.
+       (DECODE_COMPOSITION_RULE): Argument changed to rule and nbytes.
+       (ENCODE_COMPOSITION_RULE): New macro.
+       (finish_composition): New function.
+       (MAYBE_FINISH_COMPOSITION): Call finish_composition.
+       (DECODE_COMPOSITION_START): New implementation.
+       (DECODE_COMPOSITION_END): Likewise.
+       (STORE_COMPOSITION_RULE): New macro.
+       (decode_coding_iso_2022): Avoid long looking ahead while handling
+       composition, CTEXT extended segment, and embedded UTF-8.
+       (setup_coding_system): For a coding of type iso-2022, reset
+       CODING_ISO_EXTSEGMENT_LEN (coding) and
+       CODING_ISO_EMBEDDED_UTF_8 (coding).
+       (get_translation): Delete arguments last_block, from_nchars,
+       to_nchars.  Callers changed.
+       (produce_chars): Don't modify charbuf.  Adjusted for the change of
+       get_translation.
+       (produce_composition): Adjusted for the new annotation sequence.
+       (handle_composition_annotation): Likewise.
+       (consume_chars): Adjusted for the change of get_translation.
