[phobos] phobos commit, revision 1748

[Andrei Alexandrescu]

Yah, I was thinking of a unified and backwards-compatible sig:

string toString(void delegate(const(char)[]) sink = null,
     string fmt = null);

With null inputs toString works like today. When provided a sink, it 
outputs to the sink and returns null.
