[stmt.for] Missing curly brackets in for-statement translation

[Eelis]

According to [stmt.for],

for (; false; ++i) int i = 5;

is equivalent to:

{
    ;
    while (false) {
        int i = 5;
        ++i;
    }
}

which is well-formed. But this is clearly not the intent, and all compilers I tried reject the for loop above (when there is no other i around, of course).
