Use comma operator with for-initializer

[Theron Tarigo]

Input:

  int a,b,c;
  if(cond) {
    a=0,b=1;
    for (c=2;c<3;c++) ;
  }

Output:

  int a,b,c;
  if(cond)
    {
      a=0,b=1;
      for(c=2;c<3;c++)
        ;
    }

Expected:

  int a,b,c;
  if(cond)
    for(a=0,b=1,c=2;c<3;c++)
      ;
