Perhaps you're right: someone could certainly copy something from *Backtrace* to the minibuffer and edit it there. But someone else might find it convenient to edit it in *Backtrace* (in context) before copying. Dunno if that's worthwhile. The question is whether there is a real need for undo in *Backtrace*. I don't see a need for it, but the question is open, for now. Anyone see such a need?
