Hmm, I was thinking about this too, but it is not easy since we
control also the loops with goto's and updates of the loop
states. Refactoring out the inner block would mean to update state
varables via pointers and to introduce return codes which contains
control flow information. Don't think this will become easier.

We could probably merge both for-loops in one while-loop but also on
costs of code readability.
