FO Leader (Newbie) Question

Does <fo:leader> produce a space-before the line by default?

i.e.

-------------------------------------------------------------
ytuyuytuyyutyutuytyty yuyyut uytuytu uyt ytyt uuy tyut ytuy t
<!--space here-->
--------------------------------------------------------------

Is there anyway to remove the space or another method to generate the
following?

-------------------------------------------------------------
ytuyuytuyyutyutuytyty yuyyut uytuytu uyt ytyt uuy tyut ytuy t
--------------------------------------------------------------

I have been using the following code, with no space-before or space-after
attributes defined, and I get the space:
....
    <fo:table-cell>
         <fo:block text-align="center">
            <fo:leader leader-length="1.875cm"
                  leader-pattern="rule"
             rule-thickness="0.5pt" color="black"/>
         </fo:block>
      </fo:table-cell>
......

Any suggestions gratefully appreciated.

Thanks.
