Export of deadline status via ~org-batch-agenda-csv~

[Stefan van der Walt]

Hi all,

I am trying to process all of my TODOs in a script, and therefore use 
~org-batch-agenda-csv~ to export them to CSV.

I am running into two problems:

1. It seems to be impossible to get deadline/schedule information for tasks 
that have been marked as DONE and
2. There exists a ~type~ value ~past-scheduled~ for when a task's scheduled 
date has been missed, but there is no equivalent for ~past-deadline~.

(See =org-agenda.el=, docstring for ~defmacro org-batch-agenda-csv~).

I think (2) can be fixed fairly easily by adding a "past-deadline" type.  I'm 
not sure how to address (1).  Any thoughts?

Best regards,
Stéfan
