      Yes. If you plan to post to vim_dev in the future, I can subscribe you
      by hand. This way your first post there won't be moderated.

      Just in case I'm CCing this message to vim_dev. That's why I quote so
      much material, so the thread can be followed there.

      You are right, I can reproduce it here: the contents dump to the
      "foobar" file are not shown on the screen (the file is not updated) but
      are written on the file on disk. If you (like me) are using a swap file,
      then the problem is that vim works with the swap file, not the disk
      file, and the disk file is not updated until you :w it.
