If a MARC bib is modified by this batch job,
do not duplicate the item tags embedded in
it (e.g., 952 for MARC21). When modifying
a bib record, any embedded item tags must
be removed before calling ModBiblio - perhaps
this should be moved to ModBiblio itself.
Also removed an error in the job's help text.

During link_bibs_to_authorities.pl run, a bib was
observed that had both biblioitems.marc and biblioitems.marcxml
set to blank or NULL. Added check to verify that a
defined value is returned from GetMarcBiblio(); may follow
up with additional patches once it's determined how
the corrupt bib came to be loaded.
