    Fix #103: comment indentation after struct members
    
    Correctly indent comments that come after struct members that do not
    have a trailing comma.
    
    Before:
    
        struct A {
            x: u8
                // TOO FAR
        }
    
    After:
    
        struct A {
            x: u8
            // CORRECT
        }
