It is only this good thanks to feedback and help from others.

Hm. I think we might need to go over the current getinfo() options to clear
up some confusions (most of it in my head definately).
At this point, I think most of the getinfo() options give you the sizes for
the download, not for the complete remote file. I do however believe that you
may need to do a separate HEAD check on the file to get the total size of the
file, as the Content-Length: size when you get a file with a range is set to
the current size being sent, isn't it (i.e not the total size)?
You can do this yourself today by doing a HEAD and parsing the headers. A bit
more work, but nothing really tricky.

CURLINFO_CONTENT_LENGTH_DOWNLOAD is meant to be the Content-Length: (or
equivalent) size sent by the remote server.
CURLINFO_SIZE_DOWNLOAD is the amount of data actually and truely downloaded.
