Bug#654991: jed-extra: Installation fails for SLang >= 2.2.3

[Rafael Laboissiere]

Package: jed-extra
Version: 2.5.6-1
Severity: important
Tags: upstream

[ N.B.: this has also been reported against the Ubuntu package:
  https://bugs.launchpad.net/ubuntu/+source/jed-extra/+bug/882208 ]

Since SLang 2.2.3 has been added to Debian, the jed-extra package
produces the following error during installation:

=====================================================
Setting up jed-extra (2.5.6-1) ...
jed library path: /usr/share/jed/jed-extra/drop-in,/usr/share/jed/lib,/usr/share/slsh,/usr/share/jed/jed-extra,/usr/share/jed/jed-extra/utils
list_concat cannot be re-defined
Traceback: _autoload
/usr/share/jed/jed-extra/utils/ini.sl:79:<top-level>:Duplicate Definition
Traceback: evalbuffer
/usr/share/jed/jed-extra/make_ini.sl:625:update_ini:Duplicate Definition
  Local variables for update_ini:
	String_Type dir = "/usr/share/jed/jed-extra/utils"
	String_Type buf = "*scratch*"
/usr/share/jed/compile/jed-extra-preparse.sl:45:<top-level>:Duplicate Definition
=====================================================

As a consequence, the autoload commands are not executed at JED
startup, which renders the jed-extra package pretty useless (hence the
severity "important" of this bug report).

This happens because the function list_concat has been defined in
SLang 2.2.3 and it is clashing with the definition of list_concat in 
jed-extra's upstream file datutils/datutils.sl.  This has been fixed
upstream:
