top: show that truncation indicator ('+') consistently 

With a little luck, this should be the final tweak for
our support of extra wide characters. Currently, those
characters don't always display the '+' indicator when
they've been truncated. Now, it should always be seen.

[ plus it's done a tad more efficiently via snprintf ]
