On q=admin/settings "cache documentation" links to q=admin/help instead of q=admin/help/system#cache

I don't know if this is a bug, but on q=admin/settings, I followed the link labelled "cache documentation" in the form group labelled "Cache settings" and the link took me to q=admin/help where the word "cache" (or "caching") was nowhere to be found. Maybe it should link to "q=admin/help/system#cache"?
