This annoying bug bytes in `xemacs -batch -l dunnet'. Try this:
xemacs -batch -eval '(princ "foo")'
Now this:
emacs -batch -eval '(princ "foo")'
XEmacs prints an unwanted newline, while FSFmacs doesn't. I tried to
fix it by removing the \n in stream_delete_console(), but it only
fixes the trivial case above, not dunnet.
