Reformat Code for comments in select blocks

[bt]

• Plugin version (or commit hash): v0.13.1914

• IDE name and version: IntelliJ Idea 2016.3

• Java version: 1.8.0_112

• OS name and version: macOS Sierra 10.12.1 (16B2659)

• What are you trying to do?
  Using the Reformat Code feature in IntelliJ will cause comments in a select block to be indented incorrectly.

• What would you expect to happen?
  Given the following code as an example:

select {
    case <-timer.C:
// Timer reached.
}

I'm expecting the code to be formatted as follows:

select {
    case <-timer.C:
        // Timer reached.
}

• What happens?

However, the autoformatting will output it to the following:

select {
    case <-timer.C:
    // Timer reached.
}
