Paths that are directly connected to a MUX widget are not affected by changes to the MUX's control. Rather than checking if a path is directly connected each time the MUX is updated do it only once when MUX is created. We can also remove the check for e->texts[mux] != NULL, since if that condition was true the code would have had already crashed much earlier (And generally speaking if a enum's 'texts' entry is NULL it's a bug in the driver).
