+
+        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.
