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"))
