Description

I encountered some surprising behaviour when playing with radosgw and s3cmd.
You can probably make a convincing case that the fault lies with s3cmd. But other
applications could easily be wrong in the same way.

Anyway, when I perform GET /?acl or GET /ObjectName?acl on AWS S3, the response content starts like this:

<?xml version="1.0" ?>
<AccessControlPolicy xmlns="http://s3.amazonaws.com/doc/2006-03-01/">

With radosgw, the '<?xml' line is missing.

This confuses s3cmd, so that it does not understand the ACL. Any chance that radosgw could start sending
the missing line?
