/window set the status bar to [connected] whatever the connection
state, and Alt and a digit runs /window. Before /connect, both made
the status bar say [connected] while the client had no session.
/window now reads the connection state with the nick and shows
[connected] only while the client is connected, [disconnected]
otherwise. TestWindowConnectionState types /window 0 and presses
Alt and 0, connected and not, and checks the status bar.
