I stand corrected (and have edited my post above).
I'm not entirely sure how it really works, though. UK_en got me FTL, EG_en got me SEN, DE_de got me Blue - and then NewbieRunner's link (again, UK_en) got me the HON flag. Everything else I tried inbetween only got me SEN, which I already had at that point (and an error message when I tried anyway).
