That's actually a VERY intelligent point.

I'm going to make -o do the following:

- write V7 format archives (which, though part of GNU tar, actually
  goes along with the following point--after all, old pax-as-tar created
  V7 archives by default);
- write archives with "write_opt=nodir", as pax already did, and as
  specified by 4.2BSD;
- extract archives with owner/group set to invoking user, as specified
  by SUS.

This should make everyone happy.
