Adding a translation to the CLDR
Fragment of a discussion from User talk:Nemo bis
Actually I just hope that we can have a translation in every language for the language name of "zh-min-nan" (cf. the interlanguage links' tooltips of https://fr.wiktionary.org/wiki/Wiktionnaire:Page_d%E2%80%99accueil?uselang=fr : the second to last link is for "zh-min-nan", and the tooltip displays the English language name "Chinese (Min Nan)", instead of the French one.
I guess your patch will solve this issue, if I'm not mistaken.
