I've commited a tool (maintenance/transstat.php) to CVS that makes the
localization statistics prestented here:
http://meta.wikimedia.org/wiki/Localization_statistics, if any of you
have some free time to waste you could help update the current
translations or help prune old redundant messages from them (see bug
2502 (
http://bugzilla.wikimedia.org/show_bug.cgi?id=2502)).
