Subject: `sources`: set "Accept-Encoding: identity" header on HTTP requests


Setting this header is always correct, even though it is not always
necessary. But it is necessary *sometimes* to prevent servers from
sending gz-compressed files in a way that causes them to get
decompressed on-the-fly on download (i.e. "Content-Encoding: gz").
