We can submit patches for the cases where the guidelines listed in
Documentation/CodingStyle diverge from common sense. 

In _some_ cases, the text which one might put after the 80th column is
actually important to the flow of the program and really should be put
back into the 'normal' text area. That's fair enough -- I'm not arguing
that we should leave 80-column text areas behind altogether.

But in this case it's just the length argument to a memcpy, and there's
no real information there. Similarly, people have recently been observed
to start wrapping the strings in debugging printks onto a second line
gratuitously. In _those_ cases, it really is counter-productive -- it's
_fine_ if that text is off the right-hand side of the screen.

If your editor wraps it onto the next line, then that sucks -- but at
least it only sucks for _you_, and you wouldn't really benefit by the
proposed 'fix' anyway, because the proposed 'fix' is just to wrap it so
that it sucks for _all_ of us.
