It seems to fix the problems we are seeing here. But there may be a
potential problem regarding the history handling. A command is added
to the history if it is not empty. This is checked via

#if MAX_HISTORY >= 1
	/* Handle command history log */
	/* cleanup may be saved current command line */
	free(history[MAX_HISTORY]);
	history[MAX_HISTORY] = 0;
        if (len) {
            /* add command to history ... */
        
So now we may add bogus commands to the history. Maybe the check
should be changed to if (len > 0) ?
