Fix indent in trailing closure

[uk-ar]

I fixed indent in trailing closure(https://developer.apple.com/library/prerelease/ios/documentation/Swift/Conceptual/Swift_Programming_Language/Closures.html).

• expected result:

a(){
    b,c in
    |println(c)
}

• actual:

a(){
    b,c in
        |println(c)
}

Looks good, thanks!
