Hello,
Consider the following~:
(with-current-buffer (get-buffer-create "foo")
;; change a variable locally
(setq-local beginning-of-defun-function #'beginning-of-line)
;; describe a function that references the above variable
(describe-function 'beginning-of-defun)
(switch-to-buffer "*Help*")
;; go to the reference and follow it
(search-forward "beginning-of-defun-functio")
(execute-kbd-macro (kbd "RET")))
The second line is:
: Its value is nil
I somewhat expected to see:
: Its value is beginning-of-line
: Local in buffer foo; global value is nil
If the old buffer is killed before following the reference, I guess I'd
like to be warned about it and see the global value instead.
What do you think ?

So you're saying that describe-function should remember in which buffer
it was invoked, in case we use describe-variable from the resulting
*Help* buffer.
It's not a terribly bad idea, but to the extent that functions can't be
buffer-local, it'd be an ad-hoc hack. It wouldn't be the first ad-hoc
hack by the long shot, but I'm not sure I'd like to add this one.

No, it sounds somewhat confusing, so I'm closing this bug report.
