Chinese translation of shadow package

Shadow package is a very import package,but now the Chinese
translation on it is not very well.

And the manpage in it is now see very well, such as useradd: there is
a space between every 2 Chinese chars.

I have translate the package to zh_CN, and I wish somebody can review
it and convert it to zh_TW and zh_HK,
of course wish upstream can accept it. :)

I have checkout the souse of it, can notice that Chinese manpages are
not maintainted by po like some other languages.
Can you add zh_CN and zh_TW to po toolchains? I am willing to convert
current standalone manpages to pos.


Thanks to all of you.
