I hadn't realised that a <link rel="index">  element was already
output in the file header. I was thinking of the <a> elements in the
table of contents or main menu. But the <link> elements are good too.
The only change I'd make is to output a <link> element for every node
containing a @printindex, instead of just the first one. Do you think
that would be okay?
