This is part of the Emacs Starter Kit.
A single hook holding those functions which should be run in every code buffer.
We have a number of turn-on-* functions since it’s advised that lambda functions not go in hooks. Repeatedly evaling an add-to-list with a hook value will repeatedly add it since there’s no way to ensure that a lambda doesn’t already exist in the list.
