Improve LISTGROUP so as to search only within the range and not
go through all the articles.

Also fix two bugs:
 * the current group was not set if the group was empty (this
   bug has always been around);
 * the new version of LISTGROUP with its third argument (the range)
   did not work if no group was set.

END
