This is a good suggestion, one I've heard before.

I like the first idea, but the "umask"/"verbatim" thing should be a
separate option. This is to maintain consistency with other GNU
utilities like mkdir and install, which use --mode with the same
meaning as chmod.

Yes. I suggest using "/" to denote the owner or group in the archive,
and the empty string to denote the owner or group of the extractor.
This would be a pure extension to chmod's operand. Also, we can
follow chmod's lead and use : to separate the owner from the group, so
that we don't need the --group option any more. E.g.,
--owner=matt Extract as owner matt.
--owner=matt:sys Extract as owner matt, group sys
--owner=/:/ The default: extract owner/group from tar file.
--owner=: Same as --no-same-owner --no-same-group
(Of course, someone would need to implement all this. :-)
