bug#24157: Acknowledgement (25.1.50; (princ "..." t) does not go to stderr in batch mode)

[Clément Pit--Claudel]

Also:

  $ emacs --batch --eval '(progn (message "to stderr.") (princ "to stderr?" 
t))' > /dev/null
  to stderr.
  $ emacs --batch --eval '(progn (princ "to stderr?" t) (message "to 
stderr."))' > /dev/null

  to stderr.

And worse:

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

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

(which I guess suggests that 'message' is the one adding the newline, not princ)

Clément.
