I have the following problem with Emacs 24:

emacs -Q --eval \
  '(shell-command-on-region (point) (point) "cp" t t "*Messages*")' tst.txt

yields a "Buffer is read-only: #<buffer *Messages*>" error instead of
outputting the standard error from "cp" to the buffer *Messages* like
with Emacs 23.

NEWS section "Changes in Emacs 24.4" states: 
 
    ** The *Messages* buffer is created in `messages-buffer-mode', 
    a new major mode, with read-only status.

Indeed, this is a new feature.  If you want to know why it was
introduced, read this discussion:
