Right, and to some people that is, AFAIU, the most problematic aspect
of the GFDL.

Yes.  However, as I said elsewhere in this thread, GFDL proponents
claim that in practice, this isn't a problem, since normally a manual
doesn't include large fragments of code.  I don't know whether this is
true, as I personally didn't have any experience either way.  The GNU
Emacs manual, perhaps miraculously, doesn't have any problems in this
area.
