I have looked over this, and will add the patch.
Note:
While this patch is reasonable and will work, end of job detection
may may fail if there are embedded PJL JOB information in the file.
If this is the case, then the original PJL JOB will get overriden
(overrode?) by the embedded PJL JOB lines.
This why the 'dummy job at the end' was to added - make sure that
some sort of PJL JOB/PJL END causes the end of job detection to
fail.
