[logback-user] Oldest archive files not removed when using SizeAndTimeBasedFNATP when rolling over and there are multiple archive files for the oldest interval.

[ceki]

Hi Jan-Olav,

Your programmatic configuration of RollingFileAppender in conjunction
with TimeBasedRollingPolicy+SizeAndTimeBasedFNATP looks good. Most
users have a hard time with such programmatic configuration.

The other files, i.e. trace-2013-03-13-16.12.{1,2,3}, should have been
removed as well. Which version of logback are you using?
