I disagree. The use of inhibit-read-only is an implementation detail
of with-help-window (and of many other functions in Emacs); mentioning
it in the doc string will IMO have no useful purpose.
The doc string of "C-x C-q" (read-only-mode) does mention
inhibit-read-only, which is I think a much more reasonable place for a
reference to that variable.
Stefan, WDYT?
