IIRC you can use
(let* ((doc (documentation NAME))
(fd (help-split-fundoc doc NAME)))
(if fd (cdr fd) doc))
But I agree that `help-split-fundoc` is inconvenient.
Improvements welcome. Maybe it should always return a pair (USAGE
. DOC) so we could just do:
(cdr (help-split-fundoc (documentation NAME) NAME)
