Subject: speakup: Avoid crash on very long word
From: Samuel Thibault <samuel.thibault@xxxxxxxxxxxx>
commit c8d2f34ea96ea3bce6ba2535f867f0d4ee3b22e1 upstream.
In case a console is set up really large and contains a really long word
(> 256 characters), we have to stop before the length of the word buffer.
