If ``getTerminalWidth`` returns a big integer (which is the case in Behat 2.5 which overwrites the method to return ``PHP_INT_MAX`` to avoid limiting the width), the fix done in #10000 for HHVM would be needed as well. So this moves it after the condition rather than having it only for the default.
