IIUC your patch works regardless of the value of
`frame-auto-hide-function'.  The problem of your patch is that in

  (if (one-window-p) (delete-frame) (delete-window))

the window for showing the buffer may have been _reused_ in which case
deleting is certainly the wrong solution.

That's what this option has been meant for.  I can't judge what it
should default to because I hardly ever use multiple frames and never
use `dired'.

We can consider adding a third value for `frame-auto-hide-function'.

If we decide that deleting the frame is the correct solution in this
particular case, the most simple option is to call `quit-window' with
both arguments t, thus killing the buffer as well.
