Hey Michael,
you have just catapulted yourself onto the list of possible successors
when I will quit as maintainer of Org... :-)
Good work - I don't think it works completely yet, though.
When I have
* new one
<2008-10-21 Tue 08:01-11:55>
* new two
<2008-10-21 Tue 13:59-14:55>
Then I get this agenda:
Day-agenda (W43):
Tuesday 21 October 2008
8:00...... ----------------
past: 8:01-11:55 new one
11:00...... ----------------
12:00...... ----------------
13:00...... ----------------
past: 13:59-14:55 new two
15:00...... ----------------
16:00...... ----------------
17:00...... ----------------
18:00...... ----------------
20:00...... ----------------
The line at 11:00 should be gone as well.
- Carsten
