80 character column limits in code are a legacy from 80 column text displays which are a legacy of IBM's 80 column punch cards which are a legacy of Roman chariots which had two side-by-side 40 column horses
@ctrl @dotjayne Yeah, 80 characters can be pretty good for fitting on half the screen... for some screen sizes and fonts.
Really it might make more sense to automatically reflow for viewing. In some ways its quite odd that `man` will happily reflow formatted text for the size of terminal I'm using, but for source code we expect a certain width baked into the file.
Text files formatted for a specific width are pretty archaic and uncommon at this point.
