wget exits with exit code 0 even though server responded with 416

Trying to continue a partial download. Server denies range request with 416, but wget a) thinks the file is already fully downloaded, b) exits with 0 instead of a nonzero exit code.

$ wget -c http://download.java.net/jdk8/archive/b124/binaries/jdk-8-ea-bin-b124-linux-x64-19_jan_2014.tar.gz?q=download/jdk8/archive/b124/binaries/jdk-8-ea-bin-b124-linux-x64-19_jan_2014.tar.gz -O jdk-8-ea-bin-b124-linux-x64-19_jan_2014.tar.gz ; echo $?

wget cannot do anything about the rejected range request, but it should inform the caller both verbosely and with a nonzero exit code that the download failed.

In this particular corner case, the downloaded file was larger than the file on the web server for a reason unclear to me.
