I have heard from some that they ought not ever be cut, no matter the length that may be beyond the tuning post. I do not subscribe to this. There are those that believe that at some specific gauge they should not be cut under any circumstances. If you subscribe to this what is the magic gauge at which you do not? If you do lop the ends off of your strings what is your process? I have heard some horror stories of late (some of which I have been called to task on/for), and a reference/consensus thread might serve the community . . . . .
