| 27 | * Checks if array initialization contains optional trailing comma. | |

| 29 | * <p> | |
| 30 | * Rationale: Putting this comma in make is easier to change the | |
| 31 | * order of the elements or add new elements on the end. | |
| 32 | * </p> | |
| 33 | * <p> | |
| 34 | * An example of how to configure the check is: | |
