I don't know the proper way to achieve this. From reading the code, it
appears that this is handled by the indent property from the declare
form, the value of lisp-body-indent, and the value of the
lisp-indent-function property of the forms within the defun/macro being
indented.

See (info "(elisp) Indenting Macros") and lisp-indent-function in
lisp-mode.el for the details.
