    seq(1): Put separator only between the elements.
    
    - Using non-default ('\n') separator will produce an output with the
      separator at the end of the output, eg.
    
            % echo "[$(seq -s ' ' 0 2)]"
            [0 1 2 ]
    
    - The output should always be followed by a new line character. Currently:
    
            % seq -s ' ' 0 2
            0 1 2 %
    
    This change makes seq(1) to behave the same way Linux seq(1):
    
            % echo "[$(seq -s ' ' 0 2)]"
            [0 1 2]
    
            % seq -s ' ' 0 2
            0 1 2
            %
