OSX layer - command+w should kill the frame if only one window remains.

[jordwalke]

It would be very natural to osx users if command+w would kill the frame if only a single window remains.
(Super new to emacs, I apologize if I'm not using the correct terminology here).

I would like to disable command+w in emacs completely, but I don't know how.
Often when switching windows with SPC w I can hit command instead of space and it will kill my frame!

Given the lack of traction on this issue, it might seem that this behaviour is not much desired by everyone. Hence, instead of proposing an enhancement to Spacemacs, here's a piece of code that'll achieve what you want.

(defun delete-frame-if-one-window (orig-fun &rest args)
  (if (one-window-p t)
      (delete-frame)
    (apply orig-fun args)))

(advice-add 'delete-window :around #'delete-frame-if-one-window)
