   Of course.  style.9, two contrib files, sys/cdefs.h, and
probably a few others I'd leave untouched.  But that still
leaves lots of files to fix.
   From the files I've looked at already, it seems that the
most common problem is including a $FreeBSD$ tag both at
the beginning of a file and immediately following the
copyright notice.
