* Enforce consistent spacing for the open/close braces of arrays.
*

* - space between the `array` keyword and the open parenthesis for long arrays;
* - spaces on the inside of the braces for single-line arrays;
* - spaces on the inside of the braces for multi-line arrays;
* - spaces on the inside of the braces for empty arrays.
*
* Note: If 'newline' is expected and _no_ new line is encountered, a new line will be
* added, but no assumptions will be made about the intended indentation of the code.
* This should be handled by a (separate) indentation sniff.
