made default mode sensible Until now in case no mode was specified, a message would have been read from stdin but then it would fail because no recipients had been given on the cmd line. (This had been useful only if -t was given.) Now in case of no mode being specified neither address arguments or -t is given then the version message is printed, otherwise mode accept is entered (as until yet).
