Gabor, Chinese manual download links were broken, please help

In http://www.php.net/download-docs.php page, Chinese was listed, however, there are no links to the manual files. It's because the generated file names are "php_manual_zh_cn.html.bz2", not "php_manual_zh.html.bz2". I've checked to see if change 'zh' to 'zh_cn' in "$man_languages" variable in file "download-docs.php" could help, but there is no "zh_cn" entry in "$LANGUAGES" variable in "site.inc" file, only "zh". I was wondering if add an 'zh_cn' => 'Chinese' into "site.inc" and change 'zh' to 'zh_cn' in "$man_languages" in "download-docs.php" could address this issue. It may look a little bit weird, but I think to change manual Makefile to generate "*zh*" files not "*zh_cn*" files is more inconvenient. Thank you!
