The point of view of the Linux kernel is that if there is no nicer way to
persent the string, exceeding 80 characters is preferable to breaking the
string.  But here, at least if Python was not indentation sensitive, there
are much nicer ways to present the string and not exceed 80 characters.

I realize that you don't like it, although I have no idea why.  Does it
make the code slower? Less reliable? Less readable?  I doubt any of those
things.  I think that staying within 80 characters would be a much greater
benefit that all of these baseless concerns.
