It'd be probably nicer to clearly explain how encoded_length and
encoded_body_length differ (rather than the diff from the data length)

(Also... if possible we might want to update 'encoded_length' field name to
encoded_data_length together now?)

I have tried to make the comments clearer. I also renamed encoded_length to
encoded_data_length for consistency.
