I feel like this is one of the benefits of piping it all through a single grep (grep, knowing the context of multiple input files, gives you useful output). Obviously you can massage both solutions to give the others' text output, but I just felt a little cheated that my response wasn't marked correct. Hm, yeah we can probably just search for the filenames and ignore everything else to make it a little more forgiving.
