When code is a maze, smart developers make maps

Disagree. Personally that sounds like a massive barrier to reading the comment to me. Limited width column text is generally regarded as easier to read, make your comments easier to read. Especially as I probably have the code open in a limited width window, as that's what I expect from code.
