the macro language of the original ITS/RMS emacs was TECO. 
Bernie Greenberg written on Multics an MacLisp based "emacs
derived" editor, soon followed by Gosling's Moclisp based UNIX text 
editor. Gosling's emacs became the ultimative code base of RMS's 
GNU/emacs. Soon later RMS was forced to to rewrite the code base 
out of legal considerations.

Therefore you are talking about rather recent improvements and 
not about the original ITS emacs. The sources of ITS emacs are 
downloadable in the internet, as well as a lot of comments. Reading
that making clear that GNU/emacs is a different program.
