multivol piped to tar

We too had the same problem on 2 different 3b5's.  After looking
at the code I decided It wasn't that great.  The reason? Well the
code has the same problem as cpio (on the 3b5's).  It seems that
if you write a partial block on the end of the tape, the hardware
on the tape drive has problems and doesn't put an end of tape marker
out there.  This can make cpio backups no-good.
