3614	MC is unresponsive when running under tmux in Linux virtual terminal	devzero		"MC randomly stucks reading input when the following coditions met:
* MC is running under tmux or another terminal multiplexer.
* tmux itself is running in Linux virtual terminal.
* GPM is running.

MC tries to connect to GPM and then stucks reading GPM events. Under these conditions, MC is actually running in a pseudo terminal created by tmux, not in a virtual terminal, so we should not try connecting to GPM. The possible solution is to check ttyname in init_mouse(). If ttyname is /dev/tty*, it is a virtual terminal.
