>Description:

	When trying to read a tar file created by GNU-tar or Solaris's tar,
	pax asks for another archive. It seems to misinterpret the tar-header.
	Some sizes of tar's will be handled just right, others don't.

>How-To-Repeat:

	prompt> dd if=/dev/zero of=foo bs=1759830 count=1
	prompt> tar cf bar.tar foo
	prompt> pax -vf bar.tar
	-rw-r--r--  1 marcolz          wheel    1759830 Mar 27 14:52 foo
	pax: End of archive volume 1 reached
	pax: ustar vol 1, 1 files, 1761280 bytes read, 0 bytes written.

	ATTENTION! pax archive volume change required.
	Ready for archive volume: 2
	Input archive name or "." to quit pax.
	

>Fix:
	
	A work around for this specific example is to do:
	prompt> { cat bar.tar ; dd if=/dev/zero bs=512 count=1 ; } | pax -v

	But in general it seems like a good idea to just add a complete
	<blocksize> block of zeroes, i.e. 10k, so:
	prompt> { cat bar.tar ; dd if=/dev/zero bs=10k count=1 ; } | pax -v
