title: log4cplus configuration file, file max size doesn't work
body: <p>i have create a config file for log4cplus and its works but MaxFileSize don't do anything so my files keep growing without taking in considaration my limit .
  this is my code :</p>
  
  <pre><code>### logs.properties
  
  # root logger
  
  log4cplus.rootLogger=INFO, Main
  
  # specific logger
  
  log4cplus.logger.myloggerINFO, Main
  log4cplus.additivity.mylogger=false
  
  # appender that automatically rolls files
  
  log4cplus.appender.Main=log4cplus::DailyRollingFileAppender
  log4cplus.appender.Main.Schedule=DAILY
  log4cplus.appender.Main.File=mylogs.log
  log4cplus.appender.Main.Append=true
  log4cplus.appender.Main.MaxBackupIndex=100
  log4cplus.appender.Main.MaxFileSize=100KB
  log4cplus.appender.Main.layout=log4cplus::PatternLayout
  log4cplus.appender.Main.layout.ConversionPattern=%D | %-5.5p | %-20.20c | %m|%n
  
  log4cplus.logger.myLoggerName=DEBUG, R2
  log4cplus.appender.R2=log4cplus::RollingFileAppender
  log4cplus.appender.R2.File=logs/webaccess.log
  log4cplus.appender.R2.Append=true
  log4cplus.appender.R2.MaxBackupIndex=5
  log4cplus.appender.R2.MaxFileSize=5KB 
  log4cplus.appender.R2.layout=log4cplus::PatternLayout
  log4cplus.appender.R2.layout.ConversionPattern=%D | %-5.5p | %-20.20c | %m|%n
  </code></pre>
  
  <p>this is the example of list of files i get :</p>
  
  <pre><code>webaccess.log | 7kb even if max=5
  mylogs.log    | 0
  mylogs.log.2012-11-26 | 1k
  mylogs.log.2012-11-26.1   |1k
  ...
  mylogs.log.2012-11-26.45  | 1k
