This patch add indentation for Go type switch and select case 
blocks.

Current behavior
```
	var x any
	switch x.(type) {
	case int:
	println(x)
	}

	var c chan int
	select {
	case x := <-c:
	println(x)
	}
```

Correct behavior
```
	var x any
	switch x.(type) {
	case int:
		println(x)
	}

	var c chan int
	select {
	case x := <-c:
		println(x)
	}
```
