Signing issue with urlencoding

[danopia]

I tried getting a path like /2013-04-01/hostedzone/%2Fhostedzone%2FZ1LZDA11I5YD8/rrset by accident, and it broke the signature:

AwsServiceError: InvalidSignatureException: The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.

Probably need to consult more docs and/or see if the aws-fetch project handles this case better.
