Subject: [PATCH] (perl #132008) make sure the test behaves without a tty
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The test is intended to test how Term::ReadLine behaves without a tty
and mocks up an invalid tty.

Unfortunately some of the checks it does fail if the test starts without
a tty.

Modified the test to handle the lack of a tty.
