I agree with aligning parameters. (I quite like thougthbot's style as a 2nd choice).

We have aligning parameters in our ruby style guide:
```
# good
def send_mail(source)
  Mailer.deliver(to: 'bob@example.com',
                 from: 'us@example.com',
                 subject: 'Important message',
                 body: source.text)
end
```
 and I think we should be consistent with that e.g. if we don't go for aligning parameters here in erb we should change in ruby style guide also.
