In an Emacs -Q (recent CVS, NS port), doing the following right after  
startup:

   (delete-frame (selected-frame) t)

will lead to an "Attempt to delete the only frame" error.  This seems  
needless in non-X/non-Windows environments.

frame.c, delete_frame():
   /* x_connection_closed must have set FORCE to `noelisp' in order
      to delete the last frame, if it is gone.  */
   if (NILP (XCDR (Vframe_list)) && !EQ (force, Qnoelisp))
     error ("Attempt to delete the only frame");

If there are technical reasons for this, it would be good if the doc  
string for `delete-frame' was updated.

I am closing this bug as it is unlikely we're going to fix this  
problem any time soon.

At least one frame needs to be declared selected, and that frame may  
be hidden, which provides the workaround for this problem (as in  
previous versions).
