XSL: fix footnote numbers

[Jon Willeke <willeke@intersys.com>]

I'm using version 1.14 of the DocBook XSL stylesheets with DocBook XML 4.1.
 I don't like the way footnotes are rendered in HTML.  In the footnote
section at the bottom of the page, the numbers appear as superscripts.
I've commented out the <sup> tag and added a space after the number:

93c93
<     <sup>
---
>     <!-- <sup> -->
98,99c98,99
<       <xsl:text>]</xsl:text>
<     </sup>
---
>       <xsl:text>] </xsl:text>
>     <!-- </sup> -->
