[Bug-tar] [tar 1.31] aborts when extracting directory with --keep-newer-files

[kewl]

Hello,

This may be related to the bug 
https://lists.gnu.org/archive/html/bug-tar/2019-01/msg00015.html
However to make sure it is covered, I get abort as well extracting a non-empty 
directory with the following reproducible command:

$ mkdir d;touch d/file;tar cf - --no-recursion d | tar xf - --keep-newer-files
Aborted

Thanks for your consideration
Kewl
