One issue with fish_add_path at the moment is that it is sometimes a bit too intransparent. You'll try to add a path, but it won't appear - was that because it wasn't a directory, or because it doesn't exist, or because it was already included? If it isn't usable after, did fish_add_path not add it because of something or did something *else* remove it? So we give more explanations - "skipping this because it's a file", "not setting anything because no paths are left to add", ...
