Re: [PATCH RFC] git-am: support any number of signatures

Optional parameters for arguments make backwards-compatibility tricky.
In this case, the command:

  git am -s mbox1 mbox2

means "apply the patches from mbox1 and mbox2, and signoff the patches".
Under your scheme, it now means "apply from mbox2, and use the trailer
mbox1".

Thanks for saving me from typing ;-)
