It's your driver and, at the end of the day, your headache; but the very day you need to run a git bisect and you end up in the middle of one of these commits, you'll regret this statement :-) There's usually a way to make sure things continue to work even if it means duplicating some code until the conversion is completed, or adding temporary flags which get added and removed within the same series, etc. my 2 cents -- balbi
