That won't work.

And there currently is no easy to answer the question. Remember, Subversion
models the deletion of an item as the removal of its entry in its parent
directory. So there is record attached to a given line of history of the
end of that line of history.

Applications like ViewVC use a binary search to answer this question, but
ViewVC has the advantage of being server-side already. Ideally, we'd have
an RA API that answered the question, which would allow the server side to
become more optimal as we enhanced the knowledge housed in the repository.
Today, though, no such RA API exists.
