Redundant space for self invoking functions

Thank you for this CoffeeScript Formatter plugin! :)

Report a little issue regarding redundant space for self invoking functions.

Before:

``` coffeescript
(->
    # function body
)()
```

After:

``` coffeescript
(->
    # function body
) ()
```

The space between `)` and `()` is causing syntax error on compile.
