Mail: handling of pipelined commands which cross buffer boundary. Previously, pipelined commands which cross buffer boundary were rejected as too long, even if the command itself was short enough to be handled within the client buffer. Fix is to move non-processed commands to the start of the buffer after the previous command is fully processed.
