If you care so much, use a non-wrapping editor. That's what I do.

Yeah, and that's just crazy.

We all use good hardware these days, but we certainly don't have unlimited 
line length. And wrapping is ugly. So sane people (definition: "me") use 
editors that don't wrap (marking long lines at the end instead), and for 
the very rare case when I use a small terminal, I'll need to go look if I 
care (which is seldom).

Sure. Nothing fixes the problem that you need to _occasionally_ wrap.

But the real problem is that crazy people consider checkpatch.pl to be so 
important that they wrap whether it makes sense or not.

Sense. It's what some people have. Too rare, though.

I'll happily remove the checkpatch.pl limit entirely, and ask people to 
try to use common sense, though.
