First message got cut off because yanked in the above the text follows
line in a mu4e buffer, sorry!


Setting left-margin variable breaks many autoload files when installing or updating packages.

Steps to reproduce (arch linux, GNU Emacs 27.2 (build 1, x86_64-pc-linux-gnu, GTK+ Version 3.24.33, cairo version 1.17.4) of 2022-03-11)
1. Delete all installed versions of magit (our test package)
	a. for me this looks like calling M-x package-delete return magit until I can't delete anything else
2. from command line, emacs -Q
3. yank reproduction config file into a scratch buffer of clean emacs instance:

(custom-set-variables
 '(left-margin 8)
)
(setq byte-compile-warnings '(cl-functions))

;;Initialize package sources
(require 'package)
(setq package-archives
	'(
		("melpa" . "https://melpa.org/packages/")
		("org" . "https://orgmode.org/elpa/")
		("elpa" . "https://elpa.gnu.org/packages/")
	)
)

4. M-x eval-buffer return
5. M-x package-install return magit
6. Notice a bunch of a compiler warnings and errors, I usually receive something about autoloads 105
7. Examine magit-autoloads.el file
8. Notice that some of the generated autoloads have mismatched delimiters, (" appearing on the second line of an autoload, in a region that is supposed to be a comment is fairly common, like

(autoload 'magit-wip-before-change-mode "magit-wip" "\
("Commit to work-in-progress refs before certain destructive changes.

	If called interactively, enable Magit-Wip-Before-Change
	mode if ARG is positive, and disable it if ARG is zero or
	negative.  If called from Lisp, also enable the mode if
	ARG is omitted or nil, and toggle it if ARG is `toggle';
	disable the mode otherwise.

Before invoking a revert command or an \"apply variant\"
command (apply, stage, unstage, discard, and reverse) commit the
affected tracked files to the current wip refs.  For each branch
there may be two wip refs; one contains snapshots of the files
as found in the worktree and the other contains snapshots of the
entries in the index.

Only changes to files which could potentially be affected by the
command which is about to be called are committed.

\(fn &optional ARG)" 69 70 (face default) 126 127 (face default) 185 186 (face default) 242 243 (face default) 300 301 (face default)) t nil)

face default mismatched paren occurs sometimes (I've only reproduced
that with my full init.el though). These mismatched delimiters do not
appear upstream!

9. This does not necessarily break the autoload it happens to, but it will tend to break all subsequent autoloads in the file, and it is fairly difficult for a user to understand why this would happen.
10. You can toggle this error on and off by following steps to reproduce and commenting or uncommenting the left-margin line.
	a. it is important you start with a fresh instance of emacs each time, setting left-margin, commenting the line, then reevaluting the buffer will leave left-margin still set, and the error will still occur
11. This happens for a bunch of packages! org-roam, lsp-mode, magit, valign, some ivy packages, some ivy stuff, treemacs, company, the list is long.
