Interesting.  Dunno why I used that char (which I guess is HORIZONTAL
ELLIPSIS).  In my own code I in fact use "..." (3 period chars).

Maybe I tossed in an ellipsis char because others in the thread were
worried about losing mode-line space.

(FWIW, I had that ellipsis char in Emacs doc etc.  At least in the
fonts I use (fixed width) it's so tiny as to be illegible.  An
ellipsis in ordinary printed text is quite a bit wider than other
chars (which are anyway of unequal width).  That Unicode provides a
single char for ellipsis is not a reason that we have to, or should,
use it.  I think it works against readability - everywhere I've seen
it in Emacs.)
