[Koha] Add separator from fields 245a and 245c

[Javi Legido]

Hi there.

We have below XML:

  <datafield tag="245" ind1=" " ind2=" ">
    <subfield code="a">Gesti&#xF3;n empresarial. El caso de dieciocho
cooperativas</subfield>
    <subfield code="b"></subfield>
    <subfield code="c">Consultores Asociados (Coord.)</subfield>
  </datafield>

Which leads to below string both in admin and OPAC:

Gestión empresarial. El caso de dieciocho cooperativas Consultores
Asociados (Coord.)

Question: how to add a string (let's say " | ") between fiedls 245a and
245c?

Thanks.

Javier
