Not sure about the --signoff part. The committer email/name is already silently added to the commit by git even when using --author. Moreover, When reading the "
12) Sign your work " section of SubmittingPatches from the linux kernel source (
http://lxr.linux.no/linux/Documentation/SubmttingPatches ), it seems to me that using SignedOffBy is useless if the initial author of the patch didn't use it :
"The sign-off is a simple line at the end of the explanation for the patch, which certifies that you wrote it or otherwise have the right to
pass it on as a open-source patch." (snipped a lot of explanations after this sentence)
Cheers,
Christophe
