The two functions are independent, but not exclusive.

add_directory() simply creates a directory. Before adding children
or setting properties, call open_directory().

Pass it as the child_baton to open_directory(same_path,...), as the
dir_baton to change_dir_prop(), and as the parent_baton to functions
involving the dir's children.

(Disclaimer: I've written a fair bit of delta-editor consumer code,
but not driver code.)

Since there's only one baton per directory, call close_directory()
just once.
