My `among` branch fixes [[todo/backlinks_result_is_lossy]], then uses that
to provide pagestats for links from a subset of pages. From the docs included
in the patch:

> The optional `among` parameter limits counting to pages that match a
> [[ikiwiki/PageSpec]]. For instance, to display a cloud of tags used on blog
> entries, you could use:
>
>     \[[!pagestats pages="tags/*" among="blog/posts/*"]]
>
> or to display a cloud of tags related to Linux, you could use:
> 
>     \[[!pagestats pages="tags/* and not tags/linux" among="tagged(linux)"]]

I use this on my tag pages on one site, with the following template:

    \[[!pagestats pages="tags/* and !tags/<TMPL_VAR raw_tag>
        and !tags/photogallery"
      among="tagged(<TMPL_VAR raw_tag>)"]]

    \[[!inline pages="tagged(<TMPL_VAR raw_tag>)"
      archive="yes" quick="yes" reverse="yes" timeformat="%x"]]
