Subject: 24.0.92; M-w inhibits echoing of prefix arguments
Date: Mon, 05 Dec 2011 21:27:19 +0100

1. emacs -Q
2. Type `C-u' => in the echo area you see "C-u-"
3. Set the mark (e.g. by typing `C-SPC') and then type `M-w'.
4. Type `C-u' => in the echo area you see nothing, for this and
subsequent prefix arguments.  `M-x' is, however, echoed.

The above recipe did not work in my previous build from 2011-12-03,
which may implicate this change:

2011-12-05  Chong Yidong  <cyd <at> gnu.org>

	* keyboard.c (process_special_events): New function.
	(swallow_events, Finput_pending_p): Use it (Bug#10195).

However, in my build from 2011-12-03, if I disabled transient-mark-mode
before step 3 above, then `M-w' has the same inhibiting effect on prefix
arguments, so if the above change is involved, then only to expose the
bug in transient-mark-mode.  Yet this is a recent bug, since I did not
observe it in builds prior to 2011-12-03.
