Won't format be an empty string (rather than "<dst>") if it isn't provided?

no because: .Default("<dst>")

Do we still need this default case? It would only trigger if --format is explicitly set to the empty string, which seems like a corner case better handled by either an error, or actually printing an empty string for each edge, rather than overriding the explicit intention of the user.
