"A convenience macro for `add-hook'.
|
|
|

HOOK can be one hook or a list of hooks. If the hook(s) are not quoted, -hook is
|
|
appended to them automatically. If they are quoted, they are used verbatim.
|
|
|
|
FUNC-OR-FORMS can be one quoted symbol, a list of quoted symbols, or a series of
|
|
forms. Forms will be wrapped in one lambda. A list of symbols will expand into a
|
|
series of add-hook calls.

|
