keyword=value in debian/changelog

[Rafael Laboissiere <rafael@icp.inpg.fr>]

I have seen debian/changelog files in some packages in which the keyword
`closes' is set at the first line of new entries.  However, the
packaging-manual (version 2.4.1.2, section 3.2.3) states that:

   urgency is the value for the Urgency field in the .changes file for
   the upload. See Urgency, subsection 4.2.15. It is not possible to
   specify an urgency containing commas; commas are used to separate
   keyword=value settings in the dpkg changelog format (though there is
                                                               ^^^^^^^^
   currently only one useful keyword, urgency).
   ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Is the `closes' keyword some new useful, undocumented feature of the
packaging/uploading system or are the maintainers just using it to
highlight which bugs were closed?
