Problems with curly braces in some cases

Here is a sample code that, when formatted with default settings, does not change in any way.

```php
<?php
// case 1
if (true) {return;}

// case 2
if (true) {return;
}

// case 3
if (true) {
    return;}
```

I believe that for case 1 this is OK.

And for cases 2 and 3 the result should be like this?

```php
<?php
// case 2, 3
if (true) {
    return;
}
```
