I would like to be able to log events from within an appender. I've always been surprised there isn't more support for this. Obviously to avoid re-entrancy, an appender must ignore events it generated itself, and should not generate events before log4net has been successfully configured.

The following commit will give you an idea of what I'm thinking of: https://github.com/apache/log4net/commit/9dc3ed9ae079d9abeacdf86c380b17efff4b3a97?w=1 Is this something we should support? Or is there some gotcha I'm missing? BTW if you look at the above commit without the ?w=1 suffix, you'll see whitespace differences in the Flush method. I think the .gitattributes file needs to add rules for converting spaces to tabs.
