I fixed this by removing my old emacs dock icon, putting a new one back
in, and then editing its settings to change "-emacs-real" to "emacs" in
the launch commands.  So I guess most of the problems above were because
of the stale item, and the only remaining issue for new users will be
having the launch commands be "-emacs-real" by default.

I worked around this by setting Emacs.title in ~/.Xresources.
