Subject: 24.0.50; Nextstep: Can't copy and paste null characters
Date: Fri, 28 Jan 2011 23:41:08 +0100 (CET)

Starting with .../Emacs.app/Contents/MacOS/Emacs -Q:
Type these characters in the *scratch* buffer:
abc C-q C-space def
so you now have a line looking like
abc^@def
with the ^@ representing a null character.
Now type the characters C-a C-k C-y
which should kill the line and then yank it back.

Expected result: The line is unchanged.
Actual result: Only the letters abc are yanked back.
The null character and the following characters are lost.

(I discovered this when I found myself unable to copy the debugger
buffer, which happened to contain bytecode snippets which had null
characters in them.)
