Summary:
If you put a comment after a break statement in a switch, it causes Xcode to auto-indent the line differently than without a comment.

Steps to Reproduce:
1. Copy and paste the following code into a Swift file in Xcode, or open the attached playground:

// Select all and use Control-I to apply auto-indenting in Xcode 9

// This switch statement looks OK
switch true {
case true:
    break
case false:
    break
}

// this switch statement is
switch false {
case true:
break // a comment causes the break to not auto-indent correctly
case false:
    break // but not in this case
}

// END CODE BLOCK

2. Select all of the code.
3. Type Control-I to auto-indent the code. Nothing should change, because the code is already formatted the way Xcode likes to format it.

Expected Results:
All of the break statements are indented from their parent case statements.

Actual Results:
The first break with a comment is outdented. The second break is not outdented.

Version:
Xcode 9.0 (9A235)
