Summary: 1.4.1: check_ntp logic incorrect with >1 peers

Initial Comment:
After finding a matching entry and recording the
jitter, the loop parsing the ntpq output (below) should
exit.  Otherwise, it will read the next line, that line
will not match the regex (since it is not the sys.peer
or pps.peer), and $jitter will always be set to '(not
parsed)' (which is what we see with every test).

                        # match sys.peer or pps.peer
                        if
(/^(\*|o)([-0-9.\s]+)\s+([-0-9A-Za-z_().]+)\s+([-0-9.]+)\s+([lumb-]+)\s+([-0-9hm.]+)\s+([-0-9
.mh]+)\s+([-0-9.]+)\s+([-0-9.]+)\s+([-0-9.]+)\s+([-0-9.]+)/)
{
                                $syspeer = $2;
                                $stratum = $4;
                                $jitter = $11;
                                print "match $_ \n" if
$verbose;
                                if ($jitter > $jcrit) {
                                        print
"Jitter_crit = $11 :$jcrit\n" if ($verbose);
                                        $jitter_error =
$ERRORS{'CRITICAL'};
                                } elsif ($jitter >
$jwarn ) {
                                        print
"Jitter_warn = $11 :$jwarn\n" if ($verbose);
                                        $jitter_error =
$ERRORS{'WARNING'};
                                } else {
                                        $jitter_error =
$ERRORS{'OK'};
                                }

                                print "No match!\n" if
$verbose;
                                $jitter = '(not parsed)';
                        }

1381801 does not solve the problem.
The expression
(/^(\*|o)([-0-9.\s]+)\s+([-0-9A-Za-z_().]+)........
needs to be extended to 
(/^(\+|\*|o)([-0-9.\s]+)\s+([-0-9A-Za-z_().]+)........
so that output like
     remote           refid      st t when poll reach   
delay   offset  jitter
