When the formatted content has non-zero length, RGWFormatter_Plain::get_len() method returns its size minus 1 byte. It leads to wrong behaviour when the method is used to generate "Content-Length" HTTP header. Please refer to: https://github.com/ceph/ceph/blob/master/src/rgw/rgw_formats.cc#L153.

The behaviour could be seen with following patch applied: https://github.com/ceph/ceph/commit/9357a669ead149f264370af32556786563e377f6.
