I wrap them all the way. I have it on an old Bianchi mountain bike with a 9sp cassette with Suntour bar ends. It works beautifully. No problems what so ever. I can't tell a difference between doing it that way or with down tube shifters. There is a little more friction, but I can't tell in use. I do it this way, because I like the looks of it better than when the cables exit before the bend.
