Use a two pass strategy
First we create a new opts tree from oldopts removing/commenting
the options as indicated by the contents of newopts
Second we fill in the new opts tree with options as indicated
in the newopts tree (this is because entire (sub)sections may
exist in the newopts that do not exist in oldopts)
