12.1 and for-loops

[gs]

Given the code:

Code:

void f()
    {
    int i, j;
    for( i =0, j = 0; i < 10; i++, j++ ) {}
    }

does rule 12.1 'advise' (instead of 'require') I place '()' around the for-loop initializers? In other words, to what extent does this rule apply in the head of a for-loop? The precedence relied on is the precedence of the '=' operator with respect to the ',' operator.
