Not arguing with that, but in this particular case the warning seems
counterproductive to that goal, especially compared to the
DEEP_INDENTATION warning.  More subjective or "to taste" issues tend
to have lower severity in checkpatch.  And CodingStyle *already* says
"unless exceeding 80 columns significantly increases
readability"
