ForceCuddleErrCheckAndAssign only for single lines

[bombsimon]

Currently ForceCuddleErrCheckAndAssign enforces errors to be cuddled with the assigning statement no matter how many lines it spans over. While my idea was to enforce this:

err := json.Unmarshal(body, &data)
if err != nil {
    panic(err)
}

This is now also enforced with ForceCuddleErrCheckAndAssign set to true:

err := db.
    Where(&SomeType{
        SomeColumn: true,
    }).
    Preload("AnotherTable").
    Find(&data).Error
if err != nil {
    panic(err)
}

Since the err assignment spans over so many lines I think it should be optional or configurable to leave a space between the assignment an if statement even when ForceCuddleErrCheckAndAssign is set to true.
