Is requesting the resource-walk something you can do by reading our
include/svn_*.h functions and calling an svn_foo function, or just
something you can do by reverse-engineering our WebDAV protocol (or
admittedly reading the notes/webdav-protocol doc)? If the latter, I
don't see why we need to support it; I thought our policy has always
been that we make it as easy as possible to bind to us, but if you
want to reverse-engineer, goo luck.
