Sorry, it fell through the cracks.

However, I was about to push it now, but compiling the modified
version generates warnings:

    ELC      emacs-lisp/checkdoc.elc

  In checkdoc-ispell-docstring-engine:
  emacs-lisp/checkdoc.el:2161:47:Warning: reference to free variable
      `ispell-format-word-function'
  emacs-lisp/checkdoc.el:2162:62:Warning: reference to free variable
      `ispell-program-name'
  emacs-lisp/checkdoc.el:2163:42:Warning: reference to free variable
      `ispell-current-dictionary'

  In end of data:
  emacs-lisp/checkdoc.el:2714:1:Warning: the following functions are not known
      to be defined: ispell-set-spellchecker-params,
      ispell-accept-buffer-local-defs, ispell-correct-p

Could you please augment the patch so that these warnings are avoided?

Also, please mention the bug number in the commit log message.

TIA
