Comment describing SetVLOGLevel is not accurate

// NOTE: To change the log level for VLOG(_IS_ON) sites
//	 that have already executed after/during InitGoogleLogging,
//	 one needs to supply the exact --vmodule pattern that applied to them.
//       (If no --vmodule pattern applied to them
//       the value of FLAGS_v will continue to control them.)

// NOTE: To change the log level for VLOG(_IS_ON) sites
//	 that matched a prior --vmodule pattern then the exact pattern has to be supplied again.
//       (If no --vmodule pattern applied to them before then the first matching pattern will start to control them.)
