Btw, most of the code for self-insert-command is in an internal
function, so rewriting that in Lisp is unlikely to help people
understand its internal hair.

More importantly, most of the complicated parts of the C code cannot
be rewritten in Lisp anyway, so only limited progress can be made this
way, which will not make it easier to understand the core.
