I have some problems just adding comments. Given the following test input

int one_higher(int x)
{
        return x+1;
}

and the following smpl:

@rule0@
type T;
identifier f;
@@
+ const
T f(...)
{
...
}

@rule1@
type T;
identifier f;
@@
+/* Before function comment */
T f(...)
{
...
}

then coccinelle works like expected:

 {
        return x+1;
 }

However, if I remove rule0 and only keep rule1, then coccinelle
does not add the comment before the function.
