There are too many other cases where this is needed. Expecting it to happen
"by convention" means it won't happen in many cases where it should, simply
because the idea of referencing a parent buffer was omitted.
Now if we could go deeper down, and say that `process-environment' itself is a
"buffer group-local" variable, instead of just a buffer-local variable...
I guess what I want is object-based scoping for dynamic variables, rather than
just the global/local distinction we have now.
