Performant and correct set_spans_truncated

the previous implementation used set_string_truncated. This is not only
awkward with this kind of "streaming" string (and therefore lead to an
inefficient and incorrect initial implementation) but that function also
truncates strings of width 1 when there is only a single char available.

The implementation here is performant, correct and also handles the
single width case correctly.
