I had wondered if the original form of the patch printed line numbers
rather than the actual line contents. If that were true then it'd make
sense to include comment lines. In the current form of the patch,
though, I think the output is just as readable without comment lines ---
and I'm not thrilled with having this patch materially affect the
behavior for cases where -r wasn't even specified.
