// throughout the lifetime of this object.
// The given string will be appended to; any existing data in the string will
// be preserved.
// 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.
