You don't need to generate code for those parts which haven't changed.
Isn't that very interesting information? Wasn't there some hack from
Andreas Fuchs which used macroexpand hooks to find the changed bits?
It didn't use the editor.

I don't know about Vi but many editors can't be programmed as easily
as Emacs. For those editors it's much easier if the hard work is done
by some external tool.
