[O] LOGBOOK opening

[François Pinard]

Hi, Org people.

When using SPC in the Agenda buffer (org-agenda-show-and-scrollup), the
LOGBOOK drawer is shown opened, which is not a big problem, yet a
slightly annoying one, as I'm rarely interested to see its contents at
this stage.  Moreover, the manual explains that one of the purposes of
drawers is keeping information out of sight, unless the user takes
specific action for opening it.

The above command leave the cursor on the SCHEDULED: line in the Org
buffer, which is above and outside the LOGBOOK drawer, so there is
likely no need to open it.

Is there some secret variable to prevent such opening?  (I begin to see
the pattern on the Org mode list -- someone presents a problem, another
gives the name of the variable that solves it!)
