Bug: odt export: headline links ignore description [7.8.11]

[gsmith@daed.com]

Remember to cover the basics, that is, what you expected to happen and
what in fact did happen.  You don't know how to make a good report?  See

Your bug report will be posted to the Org-mode mailing list.
------------------------------------------------------------------------

The ODT export documentation states "A link with no description and
destined to a regular (un-itemized) outline heading is replaced with a
cross-reference and section number of the heading."

However, this replacement happens even for links to outline headings
that do have descriptions--the description is replaced by the section
number. Worse, if num:nil is set in #+OPTIONS, the description is
replaced by a blank space.

Expected behavior:
[[*foo]] should result in a cross-reference to foo with the the text
being the section number

[[*foo][description]] should result in a
cross-reference to foo with the text "description"
