I don't think the size of the functions matter much. Agenda is optimized
for single day view, so it is fast in this case because it only looks
for "interesting" headlines. However, this mechanism is terrible for
multi-days agendas: Agenda treats them as multiple single days agendas,
so you end up looking again and again at the same entries.

Usually, you inline a function if you are certain funcall overhead is
responsible for the slowness.
