I have doubts about this. Maybe they did some simple variable settings, but I doubt they wrote proper lisp programs.

  That's the really cool thing about Emacs. The only difference between "simple variable settings" and "proper lisp programs" is a difference of scale, not a difference of kind. Variable settings are just as much code as anything else in Emacs.

    Indeed. (+ 1 2) is a "proper Lisp program". By having all that power available from the start, users can use as much or as little as they need and shape the tool on the fly as they work with it. It's the difference between an extensible text editor and a completely malleable one.
