Comments on lines that are within the files modified by the patch should be posted as inline

I can still add comments on lines that are within the files modified by the patch. Instead of differentiating between issues that are in the patch and outside, we might want to differentiate between issues that are in files touched by the patch and issues that are not in files touched by the patch.
