 This is another A-team sprint task.  Description copied from wiki:

 This is a continuation of #454, and is necessary to complete the
 additional NS handling (#453). We add an option flag to find(). If it
 specifies the "glue OK" mode (which is off by default), find() doesn't
 stop the search at a zone cut and tries to find the longest match, if any.
