I think this commit breaks setting up custom logs. I am using Log4j and set up my logger instances in config/environments/*.rb. This worked just fine on 1.0.10, but upgrading to 1.1.13 broke my logging. By the end of Application.initialize! my loggers had been reset back. I am guessing it was this commit that did it.

I suggest it should be reworded to use `config.logger ||= ...` so as not to overwrite others customizations.
