Almost understandable, thanks!

I'm fine with b). We could say that everything under wiki/src is
CC-BY-SA 4.0. What would this imply in terms of work?

  - Making sure that this proposal is technically correct:
    - That we are allowed to do that (and under which conditions).
    - That we can still copy stuff from wiki/src elsewhere where the
      GPL applies (in the code for example).
  - Rework /doc/about/license.
  - Add the text of CC-BY-SA under wiki/src?
  - Contact everybody who contributed to wiki/src?


Anything else?

Christopher, if you know a bit of Git and are ready to work on this it
will probably take you less time than to rephrase our warnings enough to
be legally acceptable :)
