#130 get continue does not work when redirected

[shun shino]

Steps to reproduce.

1. Create file hamandeggs.txt which contains "hamandeggs"
2. Put the file to S3
3. $ echo -n ham > hamandeggs.txt
4. $ s3cmd -c /path/to/.s3cfg get --continue s3://shino.shun.test1/hamandeggs.txt

Actual result:

$ cat hamandeggs.txt
hamhamandeggs

Expected results:

$ cat hamandeggs.txt
hamandeggs

Look into packet capture,
S3 responds 307 to GET request.
In the next GET request, no Range header is included.
So S3 responds full resource.
