bug#72049: [PATCH] Fix reference from buffer-stale-function docstring

["Daniel Martín via Bug reports for GNU Emacs, the Swiss army knife of text editors" <bug-gnu-emacs@gnu.org>]

[-- Attachment #1: Type: text/plain, Size: 423 bytes --]


Steps to reproduce the bug:

- emacs -Q
- C-h v buffer-stale-function RET

Actual results:

The docstring refers to old Emacs Info node "Supporting additional
buffers".

Expected results:

The docstring points to Info node "Reverting", in the Elisp reference
manual.

This node was moved by commit 5fe81923e5b6dbbfb623befa12a3317a7e934a63.

I’ve attached a patch that corrects the issue.

Thanks.
