[O] CLOCKSUM counts appointments excluded by tag

[Myles English]

Hello,

I am using git master from yesterday (commit 6d2a661f) and have found
that when the agenda is narrowed by tag (i.e. all appointments marked
with a certain tag are excluded), the clocksum still shows the
un-narrowed total.  Is this the correct behaviour, or a bug?

Selected variables:

org-agenda-columns-add-appointments-to-effort-sum is t
org-columns-default-format:
"%80ITEM(Task) %10Effort(Effort){:} %10Duration(Duration){:} %10CLOCKSUM"

org-global-properties:
(("Effort_ALL" . "0:00 0:10 0:30 1:00 2:00 3:00 4:00 5:00 6:00 7:00 8:00 16:00 
24:00 32:00"))

Test org file:

/ - TAB 'spouse' ;; narrow by excluding the item tagged 'spouse'

See how the 18:00 has counted the 11:00 that should have been excluded:

;;,------------------------------------------------------------------
;;| Thursday    4 December 2014                             | 18:00 |
;;|                8:00...... ----------------                       
;;| * Nail org mode bug                                     | 1:00  |
;;| * Drink tea                                             | 6:00  |
;;`------------------------------------------------------------------

I would have expected something this:

;;,-----------------------------------------------------------------
;;| Thursday    4 December 2014                             | 7:00 |
;;|                8:00...... ----------------                       
;;| * Nail org mode bug                                     | 1:00 |
;;| * Drink tea                                             | 6:00 |
;;`-----------------------------------------------------------------

and am therefore disappointed.

I haven't investigated if this happens for simple clocked time as well
as appointments yet.

P.S. Sorry for the ugly boxes, I can't remember how to get the nice
ones.
