trailing $ on Cat source <040 field>

[Jackie Shieh]

I was working with a group of records that
the cataloging source for some of them ends
with a dollar sign (see attached records):

040   $aEL$$bspa$cEL$$dDLC
040   $QD$$cQD$

Sometimes, it helps to convert MARC file
to MARCMaker format to review. When I do,
curiously, MARC::Record is not able to read
it back in as_usmarc as the trailing dollar
immediately followed by another subfield has
caused MARC::Record treat it as an empty subfield.

  <Entirely empty subfield found in tag 040>

Has anyone come across situation as such? What was
the work-around?! Thanks for any advice you may have!!
