One of the things I remember about that commentary is some newspapers print the Sunday as a three-line (as in three lines of panels) format, some print it as two lines, and there's no enforcement as to how you have to do it. Breathed said that the first line, that which usually contained a drawn title had to have an unrelated throwaway joke because he couldn't assume the papers would print it. I think Watterson talked about similar in his commentaries. I have no idea if newspapers even print Dailies/Sundays anymore, it's probably been 20 years since I've picked up a newspaper beyond looking at the local headline on the Columbus Disgrace because it was on the counter at the gas station.
