Yes, I understand this fully. The ordering rule #4 allows
change_dir_prop to be called right after open_directory or before
close_directory. However, the logic I pointed out in out-of-dateness
check is invalid in the latter case. Consider an out-of-date
directory 'foo' where it fails to:

open_directory ('foo');
change_dir_prop ('foo', 'prop', 'value'); # out-of-date

But the following order will not error out:

open_directory ('foo');
open_file ('foo/bar');
apply_textdelta ('foo/bar', ...);
close_file ('foo/bar');
change_dir_prop ('foo', 'prop', 'value');

with the file change at 'foo/bar', the node_created_revision of 'foo'
in the txn is updated and is definitely up-to-date at the last
change_dir_prop, which is wrong and allowing out-of-date editor call
to go through commit.
