OK. Can we do that in another patch? Because I feel this would make
the code a little bit more complex. Let's keep this patch as only a
simple clean-up.

To me this is necessary, because I feel hard to do any development on
un-cleaned-up code. I really don't know how to add my code without
these clean-ups, and even if I managed to do that, I would not be
happy with my code.
