Peter, Daniel, thank you for information, very useful! Now I understand how this situation has happened.
And thanks for the link to another patch. Just to be precise, that patch is
 "Make -r/-w/-v argument optional"

but here we have do_extract which is supposed to be -x (which is none of -r/-w/-v)?

Is it possible to re-write do_extract so that it is only doing what it needs to be doing: prepare_layout_for_extraction() and write_buf_to_include_args() without dealing with filenames?
