Example:
The files .well-known/config.json, .well-known/public-key.pem etc. all reside under the "hidden" folder .well-known. We would like to configure the .well-known prefix to not be skipped when deploying content to the S3 bucket.

I believe the code responsible for the skip is here: https://github.com/bep/s3deploy/blob/master/lib/deployer.go#L252
