Internally, hgweb has no special support for RSS. It's simply a style.
The rss-log/ link is in the form [<style>-]<page>/.

Implementing RSS for tags is probably a matter of copying
templates/rss/log.tmpl to tags.tmpl, fixing it up, and editing the other
templates that link to it. Same for atom. Consult paper/tags.tmpl to see
what sort of data is available in the tags page context.
