I implemented a new approach to CJK typesetting: regarding each individual
character as a separate word with a tiny optional spacing behind it,
and regarding ponctuation symbols as separate words with a larger optional
spacing behind it.  This point in view will consume a bit more memory for
large documents and it might sometimes be slightly slower too,
but it solves the issue of justifying (short) lines with no ponctuation
symbols on it.  So CJK typesetting should be high quality now.
The only remaining issue concerns ponctuation symbols at the end of lines.
