>Description:
	It seems that there is a "native" pax archive format, which is
	"identical to ustar except the default blocksize is 5120 vs
	10240 ... and there is an additional header" (qupting from irc
	discussion a few moments ago.  So, pax should recognize its own
	"native" archive format, but does not.
