Previously urls were compared but now, we're comparing uuid, root_url
and repos_relpath. Those are all already canonicalized, right? Appears
not, since a bit higher up we're doing:

repos_relpath = svn_uri_is_child(repos_root_url, url, scratch_pool);
repos_relpath = svn_path_uri_decode(repos_relpath, scratch_pool);

We probably should add a svn_relpath_canonicalize() after those and
maybe the documentation on the top of svn_dirent_uri.h should mention
that a relpath is supposed to not be encoded as an uri. And shouldn't
all relpaths, uris and dirents be canonicalized when they reach
libsvn_wc?

Cheers,
