Use k&r brace placement style

[xk0fe]

K&R style has the following properties:

• Provides symmetric size (in terms of screen space consumed) between the opening and closing syntax of a clode block.
• Forces no empty or meaningless lines, thereby avoiding artificial distance between related things that should be together.
• Consumes the minimum vertical space while keeping the opening and closing syntax of a block on separate lines from the content.

Sorry no unit tests this time. But I hope there will be no bugs.
