I am experimenting with repeat tasks. When I mark something as DONE I get:
    :LOGBOOK:
    - State "DONE"       from "TODO"       [2018-04-05 Thu 10:34]
    :END:
    :PROPERTIES:
    :LAST_REPEAT: [2018-04-05 Thu 10:34]
    :END:

But the PROPERTIES value seems unnecessary: it is implied from the LOGBOOK
entry. Can I circumvent this?
