https://lists.gnu.org/archive/html/bug-tar/2014-08/msg00001.html applied
has one remaining unexpected testsuite failure at...

 25: terminal input                                  FAILED (iotty.at:29)

which appears in the attached testsuite.log as...

Any idea why this is failing on darwin? I believe there also have been reports
of this testcase failing on Solaris 10 as well. Any fix would be appreciatd.

ps This failure occurs with either the system bash or the gnu bash 4.3.30
as the default bash/sh shells in the path.
