Two things:

1.  The test attribute won't respond properly to '>';
you should use test="position() &gt; 1".  Fun, huh?

2.  If you are looking to output literal whitespace, then use
the <xsl:text> element:

<xsl:template match="cmdsynopsis">
   <xsl:if test="position() &gt; 1">
<xsl:text>
    </xsl:text></xsl:if>
   </xsl:if>
   <xsl-apply-templates/>
</xsl:template>

That's carriage return and four space characters
inside the <xsl:text> element.
