[parameter] Broken links in documentation

[Daniel James]

I posted this to the list a couple of weeks ago, but I
think it was missed.

A few of the links in the documentation are broken, the
attached patch fixes this.

But there's still a problem because in the following
lines 'tag::name' and 'tag::index' are misinterpreted
as links in the generated documentation.

 parameter::parameters<
     required<tag::name, is_convertible<_,char const*> >
   , optional<tag::index, is_convertible<_,int> >
 > const spec;

It wasn't missed.  We're busy rewriting the documentation so
we think it's a little early yet for patches against the CVS
HEAD there really is no point in patches against the last
release.

Thanks for your effort, though.  if you'd like to review the
new docs once they're ready for 1.34, we'd appreciate it
very much.
