I was checking language names from http://www.rtt.org/ISO/TC37/SC2/WG1/639/ISO-FDIS-639-1.pdf for the Dutch Wikipedia, and there I noticed there is an error in the general file: su: is given as "Sudanese", this should be "Sundanese". I have corrected it in nl:, but I am not sure whether I am supposed to do so in en: and other languages as well, so I will ask someone else to do that instead.
