Well, current monitors are always > 80 cols unless someone has a tmux
with a gazillion windows in it (yeah, I know of a couple people who do
that :)) and at least to me, breaking the line like that looks less
readable because I need to look at the two lines to parse what's going
on.

Vs when you have one long line, so you look at

	WARN_ONCE(...

and go, oh, ok, we're warning here and nothing else. Without paying too
much attention to the actual arguments of the WARN.

But this is just me.

Thx.
