@TRon: yes that's because by going through tags/.../checkin/etc you end up at that checkin and that had a typo in the README, and this is the version of the file shown on that page. The README on the main page is the one of trunk, which has the correct(ed) URL. I would have to move the tag to a different checkin to fix this (but basically the README on this specific checkin is doomed, sorry for that).
