I just noticed that debwww's cron script 7doc currently fails while processing 
Chinese debian-faq.
So we have an even worse situation as described ~1 year ago in this report.

I analyzed the situation and found how to adapt the 7doc script to work 
correctly again.
(Details: the path for the Chinese html files within the package has changed
from ../zh_CN to ../zh_cn, so the script needs a corresponding change.
Don't know what happened exactly in the past, but this way it works for the
actual situation.)


Patch attached.
