        Support for ICCCM  Extended Segments in X selections:

        * international/mule-conf.el (ctext-no-compositions): New coding
        system.
        (compount-text-no-extensions): Renamed from compound-text.
        (x-ctext-no-extensions, ctext-no-extensions): Aliases for
        compound-text-no-extensions.
        (compound-text): Redefined using post-read and pre-write
        conversions.

        * international/mule.el (non-standard-icccm-encodings-alist)
        (non-standard-designations-alist): New variables.
        (ctext-post-read-conversion, ctext-pre-write-conversion): New
        functions.

`ctext-pre-write-conversion' is called from `writ-region' as

  annotations = build_annotations_2 (start, end,
                                     coding.pre_write_conversion, annotations);

As an irregular case write-region sometimes passes a string in
`start'.  It seems like ctext-pre-write-conversion is not prepared to
receive a string in START.
