AFAIK, Zhang Linbo and Sun Wenchang provides a package called CJKpunct,
which did exactly what you want. But the package can't be used by XeTeX
now, since it's developed for the CJK macro package and GBK encording only.

Recently I'm working on a XeTeX preprocessor for Chinese document to
solve the following problems:

1. mixed-script font selection & switching.
2. prevent extra spaces between 2 lines in Chinese
(aka. insert % at the end of line), for example:

ÖÐÎÄ
²âÊÔ

without a '%' after "ÎÄ"£¬there will be an extra space between ÎÄ and ²â,
which is usually not we want when we prefered to break the lines
manually.

3. the problem you described above, using similar way like CJKpunct.

I decided to solve those problems in preprocessor way because inner
TeX solution (write a TeX macro package for that) will be ugly and slow.
