-    // e.g. "en-us" -> "en", "us", if there are multiple dashes, the part
-    // after the second dash will be dropped, but that case doesn't exist

Nit: use "ja-jp-mac" as example? That case does exist, we just don't want to
handle it specially.

// Note: for languages like "ja-jp-mac" consisting of three parts we drop the
third part and only consider language and region codes.

[Sebastian Noack, 2014/04/10 10:33:28]

Done.

+    // e.g. "ja-jp-mac" -> "ja", "jp", note that the part after the second
+    // dash is dropped, since we only support language and region
     var [language, region] = navigator.language.split("-");
 
     if (region)
       candidates.push(language + "_" + region.toUpperCase());
 
     candidates.push(language);
 
     if (candidates.indexOf(defaultLocale) == -1)
       candidates.push(defaultLocale);
