FP with alternative token 'not'

[Paul Cornett]

It seems like 'not' isn't getting recognized here. Tricky to reproduce, it has to be in a const member function.

struct C {
    void f(int i) const
    {
        bool done = false;
        if (i == 0)
            done = true;
        if (not done) { }
    }
};

t.cpp:4:8: style: The scope of the variable 'done' can be reduced. [variableScope]
t.cpp:4:13: style: Variable 'done' is assigned a value that is never used. [unreadVariable]
t.cpp:6:9: style: Variable 'done' is assigned a value that is never used. [unreadVariable]
