Yes, I tried that at first, but soon after noticed that `matches` is an output parameter, so we would have to fix up the caller to stop making assumptions that the `--` is tacked onto the beginning.  Certainly doable, but it has potential for growing into a large CL depending on how far down the rabbit hole we'd have to go to fix everything.
