+   * The system locale's UI languages list now includes, as for that of an
+     ordinary locale, the results of adding likely sub-tags from each
+     locale name, and of removing some, where this doesn't change which
+     locale is specified. This gives searches for translation files a
+     better chance of finding a suitable file.
