Custom Haskell variables don't retain their customization

[hvr]

Experienced on haskell-mode-20151226.750/Emacs 24.5.1

After having customized a few indentation related custom variables via M-x customize-mode, I end up with the following init.el file:

(require 'package)
(custom-set-variables
 ;; custom-set-variables was added by Custom.
 ;; If you edit it by hand, you could mess it up, so be careful.
 ;; Your init file should contain only one such instance.
 ;; If there is more than one, they won't work right.
 '(haskell-indentation-ifte-offset 4)
 '(haskell-indentation-layout-offset 4)
 '(haskell-indentation-left-offset 4)
 '(package-archives
   (quote
    (("gnu" . "http://elpa.gnu.org/packages/")
     ("melpa" . "http://melpa.org/packages/")))))

However, when restarting emacs with this init.el file those variables still show their default 2-value, and customize-variable tells me that the variable's state is

Hide Haskell Indentation Layout Offset: 2                                         
   [ State ]: CHANGED outside Customize.
   Extra indentation to add before expressions in a Haskell layout list.
Groups: [Haskell Indentation]

[hvr]

I notice there's entries such as

(defvar haskell-indentation-layout-offset 2 "\
Extra indentation to add before expressions in a Haskell layout list.")

(custom-autoload 'haskell-indentation-layout-offset "haskell-indentation" t)

in haskell-mode-autoloads.el... is that supposed to be in there?

I've checked just a moment ago and it works for me.

Do you use spacemacs?

[hvr]

I don't use spacemacs, no...

I just tried on a new fresh account on a Ubuntu 14.04 VM and was able to reproduce there as well, steps I took:

• Install Emacs

$ lsb_release -a
No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 14.04.3 LTS
Release:    14.04
Codename:   trusty

$ sudo apt-get install emacs
...

$ dpkg -l emacs24
Desired=Unknown/Install/Remove/Purge/Hold
| Status=Not/Inst/Conf-files/Unpacked/halF-conf/Half-inst/trig-aWait/Trig-pend
|/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad)
||/ Name                    Version          Architecture     Description
+++-=======================-================-================-====================================================
ii  emacs24                 24.3+1-2ubuntu1  amd64            GNU Emacs editor (with GTK+ user interface)

• Then I created a ${HOME}/emacs.d/init.el with the content from this issue description and started up emacs24
• M-x package-list-packages, selected haskell-mode for install, and executed; then exited Emacs, and restarted again
• Went into customize interface via M-x customize-group haskell-indentation, and the 3 settings from the description were valued with "2" rather than "4" and had the state CHANGED outside Customize.

I currently suspect this is an autoloads-related issue/bug

[hvr]

Here's an interesting discussion regarding autoloading defcustoms: https://lists.gnu.org/archive/html/help-gnu-emacs/2007-06/msg00216.html

[hvr]

Here's another discussion pointing out that autoloaded variables are indeed a mistake in most cases: http://comments.gmane.org/gmane.emacs.devel/176796

@hvr: so we have learned by the way that you are tehe only person on this planet that tried to change the defaults :)

...or maybe just the only one who bothered to get to the bottom of it ;)
