`characterp' has undocumented optional arg 'ignore'

This may be another one of the +/- 500 `bootstrapping documentation' arg bugs...
If not, following is what I found:

---
@Circa line 313 in "../src/character.c"

       doc: /* Return non-nil if OBJECT is a character.  */)

---
(describe-function 'characterp)

;;; docstring in *Help*

"characterp is a built-in function in `character.c'.

(characterp object &optional ignore)

Return non-nil if object is a character."

---
(info "(elisp)Character Codes)")

@Circa line 313 of "../info/elisp-7" as from "./elisp.texi" of Emacs
version 23.1.50

" -- Function: characterp charcode
     This returns `t' if CHARCODE is a valid character, and `nil'
     otherwise."
