Java 14 switch expressions with many values are badly formatted

[abrudin]

When having many values covered by the same case, google-java-format does a terrible job formatting the code. Example:

public class GoogleJavaFormatFail {
  public String myMethod(final TestEnum testEnum) {
    return switch (testEnum) {
      case SOME_RATHER_LONG_NAME_1, SOME_RATHER_LONG_NAME_2, SOME_RATHER_LONG_NAME_3, SOME_RATHER_LONG_NAME_4, SOME_RATHER_LONG_NAME_5, SOME_RATHER_LONG_NAME_6, SOME_RATHER_LONG_NAME_7 -> "less than"
                                                                                                                                                                                                + " number"
                                                                                                                                                                                                + " 7";
      case SOME_RATHER_LONG_NAME_8 -> "number 8";
    };
  }

  public enum TestEnum {
    SOME_RATHER_LONG_NAME_1,
    SOME_RATHER_LONG_NAME_2,
    SOME_RATHER_LONG_NAME_3,
    SOME_RATHER_LONG_NAME_4,
    SOME_RATHER_LONG_NAME_5,
    SOME_RATHER_LONG_NAME_6,
    SOME_RATHER_LONG_NAME_7,
    SOME_RATHER_LONG_NAME_8
  }
}

This is a little sad, as the new switch statements are awesome for compile time type safety (make sure no case is missed).
