Description of problem: gdm should follow iso_3166.tab and use the shorter common_name field in iso_3166.xml when available since it is simpler. Steps to Reproduce: 1. look at language name for zh_TW in GDM Actual results: 1. "中文 (中華民國)" with tooltip "Chinese (Taiwan, Province of China)" with contradicting territories. Expected results: 1. "中文 (台灣)" with tooltip "Chinese (Taiwan)" with common territory.
Created attachment 313068 [details] gdm-lang-common_name.patch I tested this simple patch and it seems to work ok.
Committed upstream, thanks.
