commit 0432f4fe6ba9b07c17ac555beab1527d8f844234

    ol.el: Restore complete by description for insert link
    
    * lisp/ol.el (org-insert-link): Allow completion of link target by its
    description.  Almost certainly the feature was removed unintentionally.
    
    Link descriptions were added to completion options in
    the commit 1e34c5d34 Bastien Guerry,  "org.el: Fontify links to current
    buffer when inserting a link", 2012-08-03 14:08:20 +0200
    in response to

    Yagnesh Raghava Yakkala, "#+LABEL and CUSTOM_ID with reftex",

    List of description was removed from completion options
    likely because `ido-completing-read' signals an error in the case of nil
    variant (that is not uncommon for links with no description), see the
    commit 7f096ad37 Tony Day, "org-insert-link: Use ido when inserting
    links", 2012-10-12 14:39:53 +1100 and the discussion of the patch

    Since auto-desc variable added by first commit was not removed
    by second one, I assume that disabling the feature was a side effect
    rather than the purpose.
