I'd argue (but not forcefully) for just "...".  As I
mentioned, "…" is, for me, useless as an ellipsis.  I think
it must be useless for nearly everyone, with a fixed-width
font.

I imagine that I included it in the patch (it's not in my
code, which is otherwise identical to what's in the patch)
only because some were worried about mode-line real estate.

Maybe it's worth a defvar (string value), so code that wants
to tweak the mode-line can adapt it?
