Formatting.

This might seem like nitpicking, but with today's IDEs with automatic code formatting this shouldn't be an issue.
What we gain from always having correctly formatted code is that we as coders never have to think about it when writing code.
When I code in Ember I never consider the formatting. I just write the code as I want it to work and then press Ctrl-Shift-F now and again to format it. It just frees up my brain not to have to think about how it should be formatted.
But the only way this can be done is if all code already is formatted. If I were to edit this file and use the autoformat function, it would result in many more lines being committed than actually were changed. And that would mess up the history, making it's nigh impossible to follow commits and see why a certain line was changed.

Thus I'm pretty adamant about the formatting being correct.
