 KNF stands for Kernel Normal Form, but it's a shorthand for
 NetBSD's coding conventions, ref. /usr/share/misc/style.  I
 didn't follow it completely through, since this is third-party
 code. Most touch-ups were just whitespace-related (e.g. no
 whitespace after function name or casts).

 You're absolutely correct.  However, one out of two isn't all bad
 either, as "n" can never go negative. :-)  I'll remove the
 superfluous test shortly.
