Detect that GET was terminated early and retry

I am trying to download a large file over HTTP and connection is getting simply terminated by the server. With `wget` it automatically retries because it knows that download has not yet reached `Content-Length` response size. But I was hoping that this package will also retry but it seems this is not so. So I am opening a feature request to suggest that it should retry also if:
* Response had `Content-Length` header in response.
* Server is indicating it supports `Range` request header.
* Response was terminated before full response was read.
