Operator name not included in document highlights

In the following code:

class test
{
public:
    static void* operator new(std::size_t);
    static void operator delete(void*);
};

When you click on `new` or `delete` to place the cursor there, QtCreator highlights the `operator` keyword but not the operator name (i.e. not `new` or `delete`). This is also goes for other operators as well.

I think, it would be more useful if QtCreator highlighted the operator name as well as the `operator` keyword since the operator name is what is significant to the user, not the `operator` keyword by itself.

I realize, this may be problematic if the operator definitions spans on multiple lines, e.g.:

static void* operator
new
[](std::size_t);

I guess, in this case it would make sense to highlight each line separately. I.e. separately highlight `operator`, `new` and `[]` words on each line. But the most common case, when the `operator` keyword and the entire name are on the same line, should still look as a single continuous highlight.
