// error <error-code> <text>
//
// The command completed with an error.  <errno-code> is a symbolic
// error code (e.g. ENOENT); if the server doesn't support this feature,
// or if it's not appropriate for this particular message, it just omits
// the <errno-code> (in that case there are two spaces after 'error').
// Text is an error message such as that provided by strerror(), or
// any other message the server wants to use.  The <text> is like the
// M response, in the sense that it is not particularly intended to be
// machine-parsed; servers may wish to print an error message with MT
// responses, and then issue a 'error' response without <text> (although
// it should be noted that MT currently has no way of flagging the output
// as intended for standard error, the way that the E response does).
