It is such a good thing that the GNU Coding Standards (and not only them), unless I remember incorrectly, ask for 80 columns of code.

Now, in https://www.gnu.org/software/emacs/manual/html_node/elisp/Library-Headers.h= tml it is said that the FIRST line of a elisp file must start like this: ;;; foo.el --- Support for the Foo programming language -*- lexical-binding: t; -*- especially if you want lexical binding, which is NOT turned on if the setting is NOT in the first line. Now, this is not exactly a bug, but for many years (I am an old guy), I wrote code with a separate header line containing only Emacs local buffer customizations.

Hi

Many years ago we had 80 = columns and that was a GOOD THING!

It is such a go= od thing that the GNU Coding Standards (and not only them), unless I rememb= er incorrectly, ask for 80 columns of code.

Also m= any years ago, and on this I may be wrong, it was also said that the
<= div>
-*- Mode: ... -*-

line could appear within the first 10 (am I remembering right?) line= s of a file.

it is said that the FIRST line of a elisp file must start like this:

;;; foo.el --- Support for the Foo programming langu=
age  -*- lexical-binding: t; -*-
especially if you want lexical binding, which is NOT turned on i= f the setting is NOT in the first line.

Bottom line, this is just a bit of a rant, but I really like my (and, I b= elieve, many other old geezers') style of having something like

=
;;; -*- Mode: Emacs-Lisp; lexic= al-binding: t; some-var-with-a-long-name: t -*-
;;; foo.el --- The foo p= kg, which also happens to have description 79 col long.

I know it's 2021, but I still like the 80 columns.

Anything that can be done about it?

All the best
