Currently William Stevenson is working on converting minor modes to use
`define-minor-mode', so more minor mode hooks will lose an ability to be
changed using `set-variable'. I don't have an opinion whether this is
good or bad. I just discovered the inconsistency between `outline-mode-hook'
and `outline-minor-mode-hook' when trying to set temporarily them
to the same value with `set-variable'.
What I still don't understand is why some hooks have "*" in the docstring.
