What version?  What does "tar --version" show?

I haven't tried to reproduce Garrett's problem yet, but
I did just download the 8.0-CURRENT-200807-i386-disc1.iso
file that Dimitry reported problems with and extracted
the base.?? files from it.

I get the right output with any of the following:
   * bsdcpio 1.0
   * bsdtar 2.5.5
   * GNU tar 1.19
   * GNU cpio 2.6
   * FreeBSD pax

So far, I've only managed to reproduce the screwed-up output
with GNU cpio 2.9.  I'm going to dig a little deeper to see
if this is really a bug in GNU cpio 2.9 or if there's some error
in the data that all those other programs are overlooking.
