It does what you want, and omits the in-body header when it would be redundant. I think the original reason I did not make "--from" the default is that I was worried about breaking consumers which do not know how to handle in-body headers. "git am" knows how to handle them, but if you have a one-off script that parses only the mail headers, it will start claiming you as the author of every patch. E.g., if you do: git format-patch -o output ... grep -hm1 ^From: output/* right now that gets you a list of patch authors. With "--from", it would return your name N times. That's obviously a toy, but I wonder if people have scripts which behave similarly. Another way to think about it is that "--from" is a no-brainer when you really are going to email the patches (and that's why it is has always been the default behavior in git-send-email). But if you _aren't_ going to mail the patches, retaining the original headers is more convenient. It's not clear to me how many non-mail users of format-patch there are (certainly rebase is one of them, but because it uses "am" on the receiving side, I think everything should Just Work). -Peff -- To unsubscribe from this list: send the line "unsubscribe git" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
