Most important change is that C-x C-k is now bound to a keymap
with keyboard macro related commands. The original binding on
C-x C-k is moved to C-x C-k e.
from the docstring with the one that should be displayed.
(help-make-usage): Understand CL style arglists.
(describe-function-1): Adapt to the new behavior of help-split-fundoc.
(describe-variable): Use delete-region.

where the function name is `fn'.
(help-function-arglist): Follow aliases and macros.
(describe-function-1): Use keymapp.
If the docstring contains a usage info, use it even if the function is
not a subroutine. Find usage info in aliases' docstring if necessary.
(describe-variable): Get the value before setting up the *Help* buffer.
(define-minor-mode): Get rid of this silly `togglep'.
Add an explicit `toggle' argument (used for interactive calls).
Emit a warning when a nil argument turns the mode off.
