Fabian Boehm f59cdfaa8d fish_add_path: Be more informative in verbose mode
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", ...
