Download of compressed/gzipd files are incomplete

there seems to be a bug when files are gzip'd on swift.

i uploaded gzip'd files without the .gz ending onto rackspace object storage as described in:
http://docs.rackspace.com/files/api/v1/cf-devguide/content/Enabling_File_Compression_with_the_Content-Encoding_Header-d1e2198.html

when downloading it with a browser the files are saved uncompressed just fine.
when downloadig with cyberduck the files are saved uncompressed but truncated after the size of the zipped file.

We have fixed this for S3 only. See #8263.
