The reason for this behaviour is that in older versions of the 
stylesheets wrap property was hardwired into stylesheets and it was not 
possible to override it by attribute set.

It affect all monospaced verbatim elements -- namely screen and may be 
few others that I can't name from the top of my head.

HTML stylesheets translate programlisting into <pre> element. You can 
use CSS to control appearance of HTML elements. If you have browser with 
CSS 2.1 support you can use

.programlisting { white-space: pre-wrap }

AFAIK none browser support this. Instead you can try:

.programlisting { white-space: nowrap }

and modify stylesheets to substitute spaces in programlisting by &nbsp; 
and line-breaks by <br>. Try add following template into your 
customization layer:

<xsl:template match="programlisting">
  <xsl:param name="suppress-numbers" select="'0'"/>
  <xsl:variable name="id">
    <xsl:call-template name="object.id"/>
  </xsl:variable>

  <xsl:call-template name="anchor"/>

  <xsl:variable name="rtf">
     <xsl:apply-templates/>
  </xsl:variable>

  <xsl:variable name="content">
    <p class="programlisting">
      <xsl:call-template name="make-verbatim">
         <xsl:with-param name="rtf" select="$rtf"/>
      </xsl:call-template>
    </p>
  </xsl:variable>

  <xsl:choose>
    <xsl:when test="$shade.verbatim != 0">
      <table xsl:use-attribute-sets="shade.verbatim.style">
        <tr>
          <td>
            <xsl:copy-of select="$content"/>
          </td>
        </tr>
      </table>
    </xsl:when>
    <xsl:otherwise>
      <xsl:copy-of select="$content"/>
    </xsl:otherwise>
  </xsl:choose>
</xsl:template>
