Showing timestamps in agenda items

[Bryan Gardiner <bog@khumba.net>]

Hello,

I've developed a habit of typing items like this:

* Foo Event <2013-07-07 Sun>..<2013-08-07 Wed>

The effect of this used to be agenda entries that looked like:

Sunday      7 July 2013
  foo:        Foo Event ..<2013-07-07 Sun>

Saturday    7 August 2013
  foo:        Foo Event <2013-08-07 Wed>..

It worked great for long, passive events that I only wanted to see
the beginning and end of, with a terse construct.  Listing many dates
was great too, only stripping the current date for any appearance in
the agenda:

* Bar Event <2013-07-08 Mon>,<2013-07-10 Wed>,<2013-07-12 Fri>

Monday      8 July 2013
  foo:        Bar Event ,<2013-07-10 Wed>,<2013-07-12 Fri>

At some point (I think between 7.8 and 7.9) all dates stopped
appearing in the description part of agenda lines, so now all that
shows is:

Sunday      7 July 2013
  foo:        Some Event ..

This is not as useful, as I could already put dates that I didn't want
visible on a following line.  I've searched the org-adenda options but
haven't found a way to affect this behaviour.  I haven't looked at the
code yet :).  How much effort would it be to do this?  Showing all
dates in agenda descriptions would be alright too.

My next choice might be to do:

* Foo
** Foo starts <2013-07-07 Sun>
** Foo ends <2013-08-07 Wed>

But I'm open to other ideas.

Thanks,
Bryan
