tar fix

[John Collins]

I'm sorry to disagree with Guy Harris but the '-c' option of 'cpio',
and the '-ncpio' option of 'find' *ISN'T* portable as various versions of
cpio don't work where the 'sscanf' format is copied literally from the
documentation in CPIO(5 or 4 for System III or V respectively).

There should be a 'h' flag with various of the %6o options corresponding
to shorts.....

Ok it's fixed easily enough, but there are enough non-working versions about
not to regard it as portable.

		Sigh.....
