Currently not possible. Enhancement request perhaps?

Looking at the implementation, setting its 'offset' member 
seems to work. Based on example from documentation:

import std.outbuffer;

void main() {
    OutBuffer b = new OutBuffer();
    b.writefln("a%sb", 16);
    assert(b.toString() == "a16b\n");

    b.offset = 0;
    b.writefln("a%sb", 16);
    assert(b.toString() == "a16b\n");
}

Bug report perhaps? :)
