Again. Please don't do that.

A bug fix is a bug fix and a cleanup is a cleanup. Mixing both is
simply wrong. It's also completely non obvious from the subject line
that this patch contains a bug fix - minor or not is completely
irrelevant.

The order is bug fix first, then cleanup and improvements. 

Please be more careful about this.

Thanks,
