In this case, it's already a new-style event, adapted to also look like an old-style event, and we don't need to tweak it again to be a new-style event, hence this checks for already-defined new-style keys. @param observer: A new-style observer to handle this event. @param eventDict: An L{old-style }, log event. @param textFromEventDict: callable that can format an old-style event as a string.
