A custom var shouldn't be modified programmatically.

But hook should usually be modified via `add-hook'
(i.e. programmatically).

Ergo, hooks are better defined with defvar than with defcustom.

Otherwise, define 2 hooks: a defvar one, modified via add-hook, and
a defcustom one, only modified via Custom.
