Thanks, installed on the emacs-29 branch, and closing the bug.

[Message part 3 (message/rfc822, inline)]

Subject: 29.1; Fix usage of `setq-default' and add explanation
Date: Sat, 16 Dec 2023 03:18:20 -0800

In the lisp intro book, there is a discrepancy in the section "Text and
Auto Fill mode" where the first code example uses "(setq-default
major-mode 'text-mode)"[1] but in the later explanation part the
function was changed to `setq'[2].  It looks like the original change[3]
was to deprecate the usage of "default-major-mode", but forgot to update
the other part.

I have prepared a patch to make it consistent, and also added some extra
text to explain why `setq-default' is required for a buffer local
variable using a foot note.  Will add in the next mail.
