I think that this might be clear enough on its own, especially since this is the same as BSD grep on my machine. I think that part_s_ of a line indicates that behavior, but perhaps not. On GNU grep, this is:

  Print only the matched (non-empty) parts of a matching line, with each
  such part on a separate output line.

I'm happy to pick either and re-send this patch (2/2) again, if it wouldn't be too much to juggle. Otherwise, I can re-roll to v4.

Thanks, Taylor
