OK, perhaps I simplified too much. The original problem is in this
function from help-fns.el:
(defun help-do-arg-highlight (doc args)
(with-syntax-table (make-syntax-table emacs-lisp-mode-syntax-table)
(modify-syntax-entry ?\- "w")
(dolist (arg args doc)
(setq doc (replace-regexp-in-string
;; This is heuristic, but covers all common cases
;; except ARG1-ARG2
(concat "\\<" ; beginning of word
"\\(?:[a-z-]*-\\)?" ; for xxx-ARG
"\\("
(regexp-quote arg)
"\\)"
"\\(?:es\\|s\\|th\\)?" ; for ARGth, ARGs
"\\(?:-[a-z0-9-]+\\)?" ; for ARG-xxx, ARG-n
"\\(?:-[{([<`\"].*?\\)?"; for ARG-{x}, (x),
<x>, [x], `x'
"\\>") ; end of word
(help-highlight-arg arg)
doc t t 1)))))
=> help-fns.el:213:1:Warning: Unused lexical variable `arg'
though arg is assigned and read. Or am I missing something?
