Inconsistency with go fmt when formatting a select statement

[mtoader]

The following code:

package main

func main() {
select{
case a<-       1       : return a
                        case a,ok:=<-c3     :break
//
        default:return b
}
}

should format like:

package main

func main() {
    select {
    case a <- 1:
        return a
    case a, ok := <-c3:
        break
        //
    default:
        return b
    }
}

but is formatted like:

package main

func main() {
    select {
    case a <- 1:
        return a
    case a , ok := <-c3:
        break
    //
    default:
        return b
    }
}

Note: the comment should align with the break statement and not the default block.
