Thanks; I see that now (e.g. in Emacs 28.1).

BTW, there's a typo here; "of" should be "or":

 As any hook, these hooks can be set either globally
 of buffer-locally via the LOCAL argument of 'add-hook'
 ^^
 (*note Setting Hooks::) when the hook is installed.

I don't think so, FWIW.  One might _guess_ that it
means that, when used on a buffer-local hook the	
function _is_ a buffer-local function, IOW, guess
that that's the definition of a buffer-local
function.  But that's not said, AFAICT.  Please
consider adding such a definition.  (But should
such a general definition be in a node about only
_window_ hooks?)

FWIW, I see nothing (in 18.1) in node `Setting
Hooks' that mentions buffer-local functions.  All
I see mention of there is buffer-local hooks.
(That doesn't mean there shouldn't be a link to
that node -- the link is good.)
