_Very_ long (as in: many megabytes) lines are indeed rare. But what I
said was "not too short", meaning that don't try this with 5-character
or 20-character lines and conclude that all is well. Source code with
several dozens of characters are still frequent enough.

Someone already said that, and I explained why this is false.
