Contrast this:
$ emacs --batch --eval '(message "to stderr.")' > /dev/null
to stderr.
With that (it produces no output):
$ emacs --batch --eval '(princ "to stderr?" t)' > /dev/null
And yet according to the docs:
Any Lisp program output that would normally go to the echo area,
either using message, or using prin1, etc., with t as the stream, goes
instead to Emacs’s standard error descriptor when in batch mode.

What am I doing wrong?
Clément.
