True, but in general, having gotten used to LINT, usually, I would just
check notes for syntax--for instance, I might see something about
PREEMPTION and just do (while in i386/conf) grep PREEMPT NOTES.  

What's the old Calvin and Hobbes line? "Have you looked at the manual?"
"WHAT?  Do I look like a sissy?"  

You're right of course, Fred, but in honesty, it's been awhile since I
read NOTES (or LINT in the old days) top to bottom.  Heh, I was more
careful when I was a complete novice--err, not that I'm any sort of
expert now.   :)
