+1 for consistent 2 space indent 

The indentation rule given earlier the document was going to be the target of my next attack

It says...

* Align the parameters of a method call if they span over multiple lines.

    ```Ruby
    # starting point (line is too long)
    def send_mail(source)
      Mailer.deliver(to: 'bob@example.com', from: 'us@example.com', subject: 'Important message', body: source.text)
    end

    # bad (normal indent)
    def send_mail(source)
      Mailer.deliver(
        to: 'bob@example.com',
        from: 'us@example.com',
        subject: 'Important message',
        body: source.text)
    end

    # bad (double indent)
    def send_mail(source)
      Mailer.deliver(
          to: 'bob@example.com',
          from: 'us@example.com',
          subject: 'Important message',
          body: source.text)
    end

    # good
    def send_mail(source)
      Mailer.deliver(to: 'bob@example.com',
                     from: 'us@example.com',
                     subject: 'Important message',
                     body: source.text)
    end
    ```

In my opinion this doesn't increase readability much and is going to have the negative side effect of making it hard It's really hard to stay under 80 chars and making us think (:see_no_evil: The cardinal sin!!!) when we do

If everyone agrees I'll add a commit to update that section too
