[logback-user] Auto archiving log files

[Stevo Slavić]

Ah, full path has to be specified in FileNamePattern even if it is
same as for log File - not DRY. Expected that if in FileNamePattern a
file name without path is specified, same directory as in log file
would be used. This is consistent with case when both File and
FileNamePattern don't contain path elements as both log file and
compressed log file would be stored in same, current working
directory. Is there any reason why that shouldn't be (default)
behavior? Should I file an improvement ticket for this? Couldn't find
existing one.

Regards,
Stevo.
