Bash, tar, and broken pipe

[David J. MacKenzie]

I think the reason for the broken pipe is that 'tar tf -' ignores the
padding at the end of the tar file; tar files are always an even
multiple of the blocksize in length, so they get padded with garbage
or nulls.  The 'foo' program writes the nulls into the pipe, but tar
never reads them.
