SQL*Plus format problem

The following select statement returns two rows, but when spooled to an output file an extra blank line shows up after the rows. Is there any way to stop SQL*Plus from outputting the blank line?

set verify off
set echo off
set pagesize 0
set newpage 0
set linesize 88
set trimout on
set space 0
set term off
set wrap off
clear buffer
clear break
clear columns

spool test.dat
select column_name from table
/
spool off
