Did the same test on FC19. Same result.

The patch most likely responsible is only applied to FC21/22/23 best I
can tell.

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


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?

Thanks, Achim.
