    _______________________________________________________

Details:

When wget retrieves data it passes (by default) an 'Accept-Encoding:gzip'
header. This requests the web server to gzip the data. If the server gzipped
the data, it will add an 'Encoding:gzip' header.

Upon receipt wget then unzips the data. However, it makes an exception for
gzipped Content-Types (e.g., application/x-gzip).

I think this exception is incorrect. If a web server adds Encoding:gzip, it
explicitly indicates that it did a gzip on the data, and that the received
data should be gunzipped regardless of Content-Type.
