Thanks Eli. Sorry for the false alarm.

This means that the only way to write to stderr without a newline is (let 
((cursor-in-echo-area t)) (message ...)), right? This is not ideal.

Also, I still think that this is an issue:

  $ emacs --batch --eval '(progn (princ "to stdout!") (message "to stderr."))' 
> /dev/null

  to stderr.
  $ emacs --batch --eval '(progn (message "to stderr.") (princ "to stdout!"))' 
> /dev/null
  to stderr.
  $ emacs --batch --eval '(progn (princ "to stdout!") (message "to stderr."))' 
2> /dev/null
  to stdout!

If I read what you sent correctly, the first two rpograms should produce the 
same output, and the call to princ shouldn't cause 'message' to insert a 
newline before "to stderr.", right?

Clément.
