dea49113 CheckPV fix so print actually works 4bebf135 Fixed formatting

The line

   if ( msgLevel( MSG::VERBOSE ) || m_print ) verbose() << "There are " << n << " primary vertices." << endmsg;

is nonsensical as m_print will only take effect in verbose mode. The fix is to print always() for m_print as that's the intention.
