- (GNU tar has no similar option.)
-
- o GNU tar says output old format.
- UNIX98 tar says don't chown files after extracting
- (GNU tar uses "--no-same-owner" for this).

- Many people rely on GNU tar's "l" and "o" so we can't abruptly change
- GNU tar to be compatible with UNIX98 tar.
-
- However, "o" is relatively easy: we can extend GNU tar so that "o" is
- a synonym for --no-same-owner when extracting, keeping "o"'s current
- semantics when creating. This is a bit of a hack, but it shouldn't
- break things.
