It returns every relation BUT those between A and B. (But I already said most of that in #1371.)
Amazingly, I only just realized this the other day. It seems odd to hide those items when the original game didn't have the icons BUG has showing war and WE status. While the function is called otherRelations, as you said, the 3.19 patch did add the display of WE status in one direction between the two leaders.
My thought is to allow the function to take NO_PLAYER as the second player. In that case it will show all relations. When two valid players are passed in it will show only the relations between them. I can make this an option in BULL, too. In that case, should it continue to hide one direction of the WE status and the war status of the two players? That seems like a bad idea no matter how I look at it, but maybe I'm missing something.
