I agree with you to some degree, but as per the Coding Standards we
are to use max 80-chars unless it *significantly* reduces
readability.

Breaking lines into two on a natural break only *slightly* reduces
readability, if at all to be frank.

We have MACROS which encompass many arguments and we have to draw the
line somewhere. I choose 80-chars.
