Actually I mainly wanted to unterstand the display/redisplay part,
which is not such a small bit.

It seems that I misunderstood you. I understood your advice as:
'Fiddle around with the code first, then try to understand' instead of
'First try to understand, then fiddle around with the code'.

That is not as absurd as it sounds. It shouldn't be too hard to (copy
and) modify a relatively simple DEFUN in the C code slightly. This
will probably lead to a lot of failures, but this is o.k., because
doing so is fun in itself. Based on what I learn this way I could
then carefully start to try to deal with more complex things. I am
already looking for a candidate.
