#*
#* Unit test for the COD::CIF::Tags::Print::sprint_loop_packet() subroutine.
#* Tests the way the subroutine treats values that can be interpreted as
#* 'false' by Perl under certain conditions (i.e. '0'). This test should
#* fail in case the way an empty line is checked for is changed from
#*
#* if( $line ne '' ) { ... };
#*
#* to
#*
#* if( $line ) { ... };
