Fix crash when X11 is connected via FD 0.
If stdin is not connected, the X11 connection may use FD 0, which is traditionally used for STDIN. Do not attempt reads from fd 0 unless it _really_ is connected to a terminal on stdin. Reported by https://github.com/pvanstam, thanks a lot! Closes #631 Closes #632
