change winscp.com returncode when nothing was downloaded

Hi,
it would be useful, if one could determine from the returncode of winscp.com, if all was OK but there was nothing found to download from the server. As it is now, a 1 is returned in that case, same as for errors.
So maybe set the returncode to 2, when all was fine and there was just nothing to download, that's not an error.
Best regards, Peter
