Those attributes control the space before and after
the display, not within it.  Does your programlisting
have any extra line breaks in it?  

<programlisting>
line 1
line2
line3
</programlisting>

The way to get no extra lines in the verbatim environment
is to write it this way:

<programlisting>line 1
line2
line3</programlisting>
