The last sentence of remove-hook's docstring puzzles me:

,----[ C-h f remove-hook RET ]
| remove-hook is a compiled Lisp function in `subr'.
| (remove-hook HOOK FUNCTION &optional LOCAL)
| Remove from the value of HOOK the function FUNCTION.
| HOOK should be a symbol, and FUNCTION may be any valid function.  If
| FUNCTION isn't the value of HOOK, or, if FUNCTION doesn't appear in the
| list of hooks to run in HOOK, then nothing is done.  See `add-hook'.
| The optional third argument, LOCAL, if non-nil, says to modify
| the hook's buffer-local value rather than its default value.
| This makes the hook buffer-local if needed.

When does remove-hook need to make a hook buffer-local to remove a
function from it?
