For other events, I do have one single "* Volleyball" heading
and multiple time-stamps for each occurrence in its body.
(method B)
Unfortunately in the agenda view, both entries are visualized
the same way. This is causing issues in certain cases.
For example, when I see an event on my agenda and I know that I
don't have time for it, I usually cancel the event right away in
my agenda.
However, when this time-stamp occured only in the body of a
heading (method B), cancelling does cancel *all* occurrences.
For example when I cancel "Volleyball" on the agenda of
2014-09-06, I'd cancel also 2014-08-30 (in the past) and
2014-09-13 (in the future).
And much worse: I do not notice my error.
There is a certain issue with this: how to determine whether or
not a time-stamp is the only one or if it is mentioned in the
heading itself.
