Subject: select-frame losing current-buffer
Date: Sun, 17 Jan 2010 18:26:34 +0000

The documentation of make-frame says that current-buffer continues to
selected in the new frame.  The documentation of select-frame doesn't
say anything about the matter, but one would normally expect that the
current-buffer should still remain the same.  However, the following
example shows that select-frame loses the current-buffer:

(defun testing ()
  (interactive)
  (let ((new-buffer (get-buffer-create " testing")))
    (set-buffer new-buffer)
    (select-frame (make-frame nil))
    (if (not (equal (current-buffer) new-buffer))
	(debug))))

I presume that the space at the beginning of the buffer name is
a partial cause of this misbehaviour.

Cheers,
Uday Reddy
