For example 

int i{10'000'000}

is formatted with unnecessary spaces so that it becomes

int i{10' 000' 000}

And for example 

int i{10'000}

becomes 

int i
   

Unknown macro: {         10'000}

And if only indenting is used it will add incorrectly indentation to the following line:

    int i{10'000};
            qDebug() << i;
