  Log:
  Fix an annoying bug in tar.  When it converted 'tar zcf' to 'tar -z -c -f'
  it forgot to null terminate the new argv[] array.  If you mixed this
  with $TAR_OPTIONS, phkmalloc and a whole bunch of other variables, you
  could end up with a segfault.  This isn't strictly a phkmalloc victory
  since tar walks off the end of an array rather than use uninitialized
  malloc memory, but phkmalloc makes it easier to provoke.
