I recall that Paul Burba added some code that does something, somewhat
like what is wanted. When you run svn status -u, and you have a file
in your WC that has been deleted in the repository, we wanted to be
able to return the revision it was deleted. The code does do this
now. I believe it does a binary search within the fs.
This was done over a year ago, but after 1.4 was released.
