Here is something that could be a bug, I cannot know at this moment, as
I am researching yet if I can use &key with Emacs's `defun':

(defun tmp-function-1 (text html &key one)
  "This one works fine"
  (message one))

(tmp-function-1 "text" "<html>" :one "Hello")

(defun tmp-function-2 (text html &key one two)
  "This one does not work, wrong number of arguments"
  (message one))

(tmp-function-1 "text" "<html>" :one "Hello" :two "But not alright")

Evaluating the last function does not work, it gives the error:

Debugger entered--Lisp error: (wrong-number-of-arguments ((t) (text html &key one) "This one works fine" (message one)) 6)
  tmp-function-1("text" "<html>" :one "Hello" :two "But not alright")
  eval((tmp-function-1 "text" "<html>" :one "Hello" :two "But not alright") nil)
  elisp--eval-last-sexp(nil)
  eval-last-sexp(nil)
  funcall-interactively(eval-last-sexp nil)
  call-interactively(eval-last-sexp nil nil)
  command-execute(eval-last-sexp)

I have tried searching the manual for Emacs Lisp for anything related to
`&key' and I cannot find any references, in my opinion the description
of `defun' in the Emacs Lisp manual is not satisfactorily.
