Looks like split of execve(2) syscall created bugs

[Maxim Sobolev]

Full patch is here: http://www.portaone.com/~sobomax/diff

Apart from fixing above mentioned bugs it simplifies the code by 
removing not really necessary gotos.

  ewww.   I don't like the idea of doing something in one module and
  undoing it in another.  It's too much of a hack.  Lets try to come up
  with a better solution.


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.
