Indeed - you might have user-defined drawers as well and they all contribute the
:END: part, so the begin part will have to be fleshed out accordingly. But the
generalization is easy and eyeballing the output is pretty effective: if you
miss some drawer types, the repeating :END: stands out like a sore thumb.
