It's not suspicious at all. Ben's recent sync of
paragraphs.el introduced some Big5-encoded Chinese characters
to the definition of sentence-end. Ironically, this is what
finally led me to the faulty font file on my machine that
produced the X server crash I described
earlier:

Ben, paragraphs.el has to be usable by non-MULE XEmacs also.
What can be done about that?
