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.

I have hard time imagining how display margins, which are purely a
display feature, could ever affect the results of byte compilation or
any other processing of Lisp programs.

Could you perhaps show a simpler reproduction recipe, one that
wouldn't require installing 3rd-part packages from the various ELPAs?
We use autoloading in many Lisp files in the core, so if the problem
is real and general enough, any Lisp file that uses autoloading should
do, right?

Thanks.

left-margin isn't a display feature, you've probably confused it with
left-margin-width.

Yes, I did.  Sorry about my confusion.

Easier reproduction (well, if you're in the development tree):

diff --git a/src/buffer.c b/src/buffer.c

and then "make ldefs-boot.el", and observe that ldefs-boot.el is broken:

(autoload 'allout-widgets-mode "allout-widgets" "\
("Toggle Allout Widgets mode.

	This is a minor mode.  If called interactively, toggle the
	`Allout-Widgets mode' mode.  If the prefix argument is
	positive, enable the mode, and if it is zero or negative,
	disable the mode.



instead of


(autoload 'allout-mode "allout" "\
Toggle Allout outline mode.

This is a minor mode.  If called interactively, toggle the `Allout
mode' mode.  If the prefix argument is positive, enable the mode, and
if it is zero or negative, disable the mode.


(Although you may find it difficult to then actually build Emacs
afterwards.)

I haven't tried debugging further -- is it obvious to anybody else
what's breaking here?

Looks like adaptive-fill?  lisp-mode defines various indent-* and
fill-* functions, so perhaps the extra open parenthesis is the
"prefix" it decides to use when filling/indenting?

Sounds likely.  I've now fixed this in the most straight-forward way I
could think of in Emacs 29 (i.e., by just binding left-margin to zero
before doing any of this stuff), and that seems to fix the problem.

Here's the reproducer I used:

(let ((left-margin 8)) (make-directory-autoloads "~/src/emacs/trunk/lisp/" "/tmp/out.el"))

I've just recomplied emacs with latest master:

```
$ git --no-pager grep "left-margin 0" 8c252e2326:lisp/emacs-lisp/autoload.el
8c252e2326:lisp/emacs-lisp/autoload.el:         (left-margin 0)
```

Build emacs with:

```
git pull; git clean -dfx; git checkout master; ./autogen.sh; ./configure --prefix="$HOME/.local" --with-pgtk; make -j$(nproc)
```
Start emacs with:
`/path_to_emacs_clone/emacs/src/emacs -Q --load ~/.emacs.d/myinit-dev.el --daemon; /path_to_emacs_clone/emacs/lib-src/emacsclient --create-frame --alternate-editor="" &`

Right after that I do:
```
(make-directory-autoloads "~/.emacs.d/straight/repos/minimap/" "/tmp/minimap-autoloads-left-margin-0.el")
```

on input:
```
$ git -C ~/.emacs.d/straight/repos/minimap/ rev-parse --short HEAD
ed74906
```

And it gives:
```

```

This grep shows the error is present:
```
$ grep -A2 "(autoload 'minimap-mode" /tmp/minimap-autoloads-left-margin-0.el

("Toggle minimap mode.
```

Initially I stumbled on that from `straight.el`:
`(straight-use-package 'minimap)` sort of command fails most of the time. With:
`Debugger entered--Lisp error: (invalid-read-syntax "." 29 56)`

```
$ sed -n '20,29p' ~/.emacs.d/straight/build/minimap/minimap-autoloads.el   
(custom-autoload 'minimap-mode "minimap" nil) 

(autoload 'minimap-mode "minimap" "\

I have no idea how to fix this issue which is presenting itself very often.
Thanks
