@footnote in HTML

[Patrice Dumas]

Hello,

Progressing in the manual, I found another discrepancy between the
manual and texi2any HTML, namely 

    In the HTML output, footnote references are marked with a small,
  superscripted number which is rendered as a hypertext link to the 
  footnote text.

While for now a footnote is rendered in HTML as an hypertext link
formatted as in Info, like <a href="...">(n)</a>.  

I am changing the code such that it is a superscript now, except 
when on preformatted, in this case it is still (n) as <sup> is not 
valid in <pre>.

Is it correct?
