I think we actually want something like this:

diff --git a/ui-refs.c b/ui-refs.c
index bdd3b2c..d3017ec 100644
--- a/ui-refs.c

-	cgit_tag_link(name, NULL, NULL, ctx.qry.head, name);
+	cgit_tag_link(name, NULL, NULL, name, NULL);
 	html("</td><td>");
 	if (ctx.repo->snapshots && (obj->type == OBJ_COMMIT))
 		print_tag_downloads(ctx.repo, name);
-- 8< --

The tag UI already does the right thing if we use "h" instead of "id".

The only thing I'm not sure about is whether we should change all tag
links to behave like this.  That would make tag decorations consistent
with branch decorations which already change the head, so I think that
is the way to go.
