Not quite. I've removed code which makes argv[0] == NULL
a special case completely from kern_exec.c, but just haven't
included relevant patch into this message since considered
it obvious. If you want, I can probably make complete patch
which will bring DF on par with FreeBSD, but I want to complete
testing and commit my changes into FreeBSD repo first.
