Looking through the manpage I found --same-owner, which would force the
unpacked file to be owned by the person that the tar file said it
should.

	# tar xz --same-owner -f /tmp/foo.tgz
	tar: foo: Cannot change ownership to uid 10107, gid 1000: Operation not permitted
	tar: Error exit delayed from previous errors

However, because you still don't have permissions...  it fails.
