Thanks.  AFAICT, this was already fixed in Emacs 30.2 and later:

	    (list
	     (if Man-sed-script
		 (concat "-e '" Man-sed-script "'")
	       "")
             (if (eq system-type 'darwin)
                 ;; macOS Sed doesn't support \o notation.
                 "-e '/^[[:cntrl:]][[:cntrl:]]*$/d'"
               ;; Use octal numbers.  Otherwise, \032 (Ctrl-Z) would
               ;; suspend remote connections.
	       "-e '/^[\\o001-\\o032][\\o001-\\o032]*$/d'")
