  67  * The caller must choose the order that entries should be scanned:
  68  * 1) JSORDER: Matched jobs are processed (by calling the "doentry()"
  69  *    routine) in the order that the user specified those jobs.
  70  * 2) QORDER: Matched jobs are processed in the order that the jobs are
  71  *    listed the queue.  This guarantees that the "doentry()" routine
  72  *    will be called only once per job.
  73  *
  74  * There is a "job_matched" variable in struct jobqueue, which is used
  75  * to make sure that the "doentry()" will only be called once for any
  76  * given job in JSORDER processing.  The "doentry()" routine can turn
  77  * that off, if it does want to be called multiple times when the job
  78  * is matched by multiple specifiers.
  79  *
  80  * The JSORDER processing will also call the "doentry()" routine once
  81  * after each scan of the queue, with the jobqueue set to null.  This
  82  * provides a way for the caller to print out a summary message for
  83  * each jobspec that was given.
