First, thanks for your contribution! While we may seem picky about process, we really appreciate your help.

Back to process: the aim is to keep each change as small as possible in order to simplify code review. The change we are discussing here, is irrelevant to the bug you are trying to fix, and thereby goes beyond the minimal change necessary; this we call "code churn". So for bug fixes, please try to keep the changes as minimal as possible.
