bug#18039: 24.3; Broken docstring in cl-style functions

Certain combinations of normal function args with &key args result in
broken docstrings for functions defined with `defun*'.

| Return or insert PlantUML skinparam.


signature looks like this:

(defun* puml-skinparam (key-val-strg &key elem (crlf "\n") ins)

thus the bug seems to be in the combination of normal args
'key-val-strg and &key args with default values '(crlf "\n").
