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