Just for the record: the claim comes from a collection of grammatical
additions compiled by ter'eS.

> Adverbs with 'e' come after the object sentence and before the 'e', e.g.
> paw Duj wej 'e' vIlegh "I haven't seen the ship arrive yet". [HQ v1n2p11]
When the document was copied into the wiki, the typographical conventions used by ter'eS were lost. This grammar addendum (6.2.5/1) was set in italics, which he used to indicate "accepted usage", rather than being a specific quote. The citation is clearly in error: Captain Krankor's HolQeD article in that issue regarding adverbial placement in a Sentence as Object is on pages 4 and 5, and page 11 is in the middle of an interview David Barron did with Marc Okrand.
