An archive that does not have sgid that is extracted in a directory with sgid set does not end up having its sgid set since the targetpath is chmod with the mode of the tarinfo. (Lib/tarfile.py#L2277) 

For comparison, an archive extracted with tar has the sgid bit set.

I added a patch as attachment to gather comments before making this PR.
