As I realized, that Corinna is using "the latest and the greatest" of 
the
Fedora distribution, I go myself

      tar-1.27.1-8.fc21.i686.rpm

and extracted the tar program from it.

Again using FC19, but now the tar program that I extracted:

As noted by Achim, this modification of tar took place in July 2015.

That tells it all, does it not, Corinna?
