This would delete a stand-alone frame and not iconify it.

We could give `quit-window' a third argument telling it to iconify the
frame instead of deleting it or add an option to deal with this case.
Since I still intend to eventually replace window excursions by
`display-buffer' + `quit-window' (which will probably take years) some
general pattern would be useful anyway.
