In emacs --batch (also, emacs --script),
(message "My Message")
will print "My Message" to standard error (file descriptor 2) along with a trailing newline.
What if I don't want the newline? I see that theoretically,
(princ "My Message" standard-error)`
would work, if
standard-error were defined.
standard-input are defined, however.
Is this even possible?
