@simontatham I did a similar thing for #emacs back in the day. This seems to be the version I have in my drafts (I can't find the finished one)

Emacs is my Editor; I shall not want.
It maketh me to edit in fontified buffers;
It recovereth my files: it indenteth my code in the styles of righteousness for GNU's sake
Yea, though I walk through the memory in the core of death, I will fear no evil-mode, for thou art with me, thy point and thy mark they comfort me
Thou preparest a *scratch* before me : thou wrappest my code in parens; my integers floweth over.
Its docs shall inform me all the days of my uptime: and I will edit in the process of Emacs for ever
