I think it's just a matter of you saying how you want to be referred to in the author field of the git commit :) But I think it requires a "name <email>" format.
indent is a hack from the 70s, but it can be made to produce fairly style-complaint formatting if you use it with the profile that you can find under share/examples/indent/indent.pro.
Generally we apply rules from style(9) but we also apply the existing style from a file to new code in that file. Since the two don't always agree, we sometimes reformat existing code to be style(9)-compliant and then add the new code.
I though "git format-patch" will do the right thing here. But anway "Goran Mekić <firstname.lastname@example.org>" is prefered.
I didn't know there are differences between indent(1) and style(9). I am now using profile from examples and the following is the product of it. I see there's vim integration with style(9) so I'll try to incorporate it into my own config.
