How to let curl to skip a already finished file when using the -C - option.

Hi all,
The curl manual said that:
Use "-C -" to tell curl to automatically find out where/how to resume
the transfer. It then uses the given output/input files to figure
that out.
So I tried the following command to test it:
curl -C - -O http://ftp.cn.debian.org/debian/dists/Debian7.8/Release
The issue is:
If the file doesn't exist or the file is leaving from the previous
aborted transferrings, this command can give the correct result file.
But, if the file already has been downloaded successfully, the above
command will append something like this behind the file's end:
--------
<html>
<head><title>416 Requested Range Not Satisfiable</title></head>
<body bgcolor="white">
<center><h1>416 Requested Range Not Satisfiable</h1></center>
<hr><center>nginx/1.6.2</center>
</body>
</html>
--------
As you can see, in this case, the curl give a error result based on its
judgment of where/how to resume the transfer.
So, how to let curl automatically skip the downloading for this case?
Is this possiable?
