Broken zh_CN cross-references

[Brendan O'Dea]

Hey folks.  I have a translation issue: I'm generating a zh_CN localised page using po4a and the word splitting is breaking some of the cross-references.

Example .texi and .info files attached.  To reproduce: open the .info file, and jump to the node: "调用 help2man".  The first cross reference in the section discussing "--name" splits across two lines for me, so instead of attempting to lookup the node "包含文字" (which does exist), it tries to lookup "包含 文字", which doesn't.
