Talk about new school... all those double dashes make my head spin!
So here's how I'd do what you outlined:
install -d -oadm a
install -d -ogames a/b
install -d -onews a/b/c
install -d -ouucp a/b/c/d
tar -cvf test.tar a
rm -rf a
tar -xvf test.tar
tree -u a
[r...@zeus ~]# tree -u a
a
`-- [games ] b
`-- [news ] c
`-- [uucp ] d
3 directories, 0 files
I suspect that in the compatibility mode for geezers like me who haven't
fully graduated to the endless double-dash argument scheme, there's an
implied -p (or for you Gnu kids, --preserve-permissions) that sets not
just the permissions of the specified directory, but also the ownership
of the parent directories.

I wonder why GNU tar doesn't set the owners when it creates the
directory hierarchy in the second case.
