Hi,

I think I hit on a bug in GNU Emacs 24.0.95.1 (x86_64-unknown-linux-gnu,
GTK+ Version 2.24.10) of 2012-04-02.

echo -n rms > rms
chmod u=r rms
emacs -q
eval: (setq require-final-newline 'visit)
C-x C-f /tmp/rms RET

contains `find-file-noselect-1: Buffer is read-only: #<buffer rms>'

Emacs tries to add a newline to the (read-only) buffer.  Here's a quick
