* The sniff allows for having different settings for:
|
|
* - 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.
