Coming from gnuclient, delete-frame would only delete the frame.
emacsclient seems to work differently. delete-frame also deletes the buffer that was specified when creating the frame. Is there a command to get the gnuserv behavior - kill the frame but leave the buffer open. Why I want this: As I edit many files, I may have 20-30 frames. Eventually, I want to kill some of those frames. But I still want all the open buffers.
