 |Yep.  Old POSIX tar just coughed up a one line pax_global_header file :

 |Perfectly harmless feature.  Thank you for the detailed reply.

Does not look harmless on some BSD unless thorougly inspected
iirc.  Since 2013-09-13 ([9c1375a7]) i thus repack balls

      # Repack with standard tar(1) to avoid new-style headers
      ${git} archive --format=tar --prefix="${PROGRAM}-${REL}/" v${REL}.ar |
         ( cd "${TMPDIR}" && ${tar} -x -f - )
      cd "${TMPDIR}"

      ${tar} -c -f "${PROGRAM}-${REL}.tar" "${PROGRAM}-${REL}"

NetBSD tar for example might say[1], which is frightening.

    "%s extended headers posix ustar archive."
		    " Extracting as plain files. Following files might be"
		    " in the wrong directory or have wrong attributes.",
