The former is defined with (defvar ... "*...").
The latter is not defined anywhere, but as define-derived-mode says
about hooks and has been covered several times:
No problems result if this variable is not bound.
`add-hook' automatically binds it. (This is true for all hook variables.)
I would says it's not very useful to pass a hook to set-variable anyway,
since you need to type a lisp expression, and probably should use
an explicit add-hook statement.
