+Find the given $subfield in the given $tag in the given
+MARC::Record $record.  If the subfield is found, returns
+the (indicators, value) pair; otherwise, (undef, undef) is
+returned.
+
+PROPOSITION :
+Such a function is used in addbiblio AND additem and serial-edit and maybe could be used in Authorities.
+I suggest we export it from this module.
