Subject: Remote console: more output discrepancies

The remote console continued to have issues with its output.  In this case CLI
command output would either not show up (if verbose level = 0) or would contain
verbose prefixes (if verbose level > 0) once log messages were sent to the
remote console.  The fix now now adds verbose prefix data to all new lines
contained in a verbose log string.
