Message:
And, three comments earlier you said it does. curl will only decompress
automatically when given the --compressed option. Otherwise, it returns the
raw contents. Have you found documentation that suggests otherwise?

Message:
I expect than libcurl will detect the presence of "Content-Encoding: gzip"
and uncompress gzip data automatically when writing to a file.

Message:
curl -v -O --compressed works fine, curl writes uncompressed data

Message:
Can you be more specific? How does it not decode the response body? What
does it output given the command: curl -v -O --compressed
