Toby, --no-same-permissions is not supposed to disable restoring
of directory metadata from the archive. Moreover, this option
does not work for an ordinary user: it is intended for root use
only. From `info tar':

     When extracting an archive, subtract the user's umask from files
     from the permissions specified in the archive.  This is the
     default behavior for ordinary users; this option has an
     effect only for the superuser.

(I agree that the option name is rather misleading)

To avoid restoring directory metadata use --no-overwrite-dir option.
