When would this "else" case trip?  Would it be safe to make it
return an error message, or even to do something like the following?

	sub canonicalize_path {
		my $path = shift;
		$path = _collapse_dotdot($path);

		# Subversion 1.7 split svn_path_canonicalize() into
		# svn_dirent_canonicalize() and svn_uri_canonicalize().
		if (!defined &SVN::_Core::svn_dirent_canonicalize) {
			return SVN::_Core::svn_path_canonicalize($path);
		}

		return SVN::_Core::svn_dirent_canonicalize($path);
	}

Thanks,
Jonathan
