Indent should still decrease when chaining methods on the end of curly braced block

As a disclaimer I feel I must note that this is my first ever attempt at contributing to open source software, so if I went about something incorrectly please let me know so I don't repeat it in the future.

I write a lot of RSpec tests, and the following shows up in my code quite a bit.

``` ruby
expect {
   some_action
}.to change { some_attribute_of_something }.from( nil ).to "Super Awesome"
```

The issue that I've addressed here is that the above code always comes out as the following:

``` ruby
expect {
   some_action
   }.to change { some_attribute_of_something }.from( nil ).to "Super Awesome"
```

The indenting scheme makes it look at first glance like the stuff thats chained onto the block is in it. I used to use TM1 and never had this issue, it only showed up once I started using TM2. I'm not entirely sure what changed, but I've been using this fix for about a week now without any adverse side effects I could notice.

Thanks for taking the time to look at this pull request.
