Is a few extra bytes passed through to the app significant? Neither
method can control exactly how much data is transferred from the server,
and even --max-hard-filesize is going to return a the full data frame (which
is seldom going to exactly match the requested size). There are probably
several more KB (even hundreds of KB) in transit from the remote server
depending on the TCP window size that the app can do nothing about.
