@hisham_hm me neither, I just came around it a while ago, and had to think about this because you mentioned whitespace at the end of a line :)
@hisham_hm also, since I often check patch files into Git, I have learned to ignore Git's nitpickery about mixing tabs and spaces and whitespace at the end of a line etc.
@daniel_bohrer no, that's a first! I'm not very knowledgeable on the ins and outs of email headers
