[fpc-devel] Method for write string into TStreamt

[Dmitry Boyarintsev]

How about introducing a default parameter?
The parameter keeps the method backward compatible, allowing write a string
without the prefix.

public procedure TStream.WriteAnsiString(
  const S: string;
  withLength: Boolean = true;
);

thanks,
Dmitry
