[O] [PATCH] Let org-agenda-time-grid control if the grid is displayed

[Christophe Junke]

* lisp/org-agenda.el (org-agenda-list): ensures that the
list returned by org-agenda-add-time-grid-maybe is appended
to rtnall before checking if the latter is emtpy.

In the case where rtnall is empty (no item for current day),
we do not call org-agenda-add-time-grid-maybe.  This seems
bogus because that function is already computing whether the
time grid must be included, and does so according to the
user's preferences.

In particular, the org-agenda-time-grid variable has a
'require-timed' parameter controlling the visibility of the
time grid.

So, this patch :

 - removes the premature check for rtnall being empty,
 - inconditionally calls org-agenda-add-time-grid-maybe,
 - and finally checks the emptiness of the resulting list
   before pretty printing.
