 // the string itself, and the user must ensure that the string stays alive

 // The given string will be appended to; any existing data in the string will
 // be preserved. The caller should reserve() the amount of data in the string
 // they expect to be written. We will resize if necessary, but that's slow.
 //
 // Note that when canonicalization is complete, the string will likely have
 // unused space at the end because we make the string very big to start out
 // with (by |initial_size|). This ends up being important because resize
 // operations are slow, and because the base class needs to write directly
 // into the buffer.
 //
 // Therefore, the user should call Complete() before using the string that
 // this class wrote into.
