Additionnaly diff/merge tool tend to be inconsistent. So it looks good on your editor, but when I am doing your code review, alignement is totally broken. In theory, it should be easy enough to ask people to have consistent settings across all tools, but it is a bit like herding cats. Sadly most people do not even realize it could look differently without their settings. (I could ignore whitespaces when doing reviews but this is an open invitation to break everything)
