bug#54288: 28.0.91; which-func documentation error

[sebastian--- via Bug reports for GNU Emacs, the Swiss army knife of text editors]

In which-func.el there is the following function:

(defun which-func-update ()
  "Update the Which-Function mode display for all windows."
  ;; (walk-windows 'which-func-update-1 nil 'visible))
  (let ((non-essential t))
    (which-func-update-1 (selected-window))))

The doc string is incorrect, since the function only updates the selected window. In fact the doc string is commented out on the 27.2 branch, along with the walk-windows implementation. It's unclear to me from the git history why this implementation for all windows was commented out in the first place, but at the very least the doc string should be updated to correctly reflect the current implementation.

Thanks.

Sebastian

I've now done this in emacs-28.
