Reformat regular diff patch to git format

Question

Is there an easy way to reformat a regular (unified) diff patch into a git-format patch? What I want to do, is take a regular patch someone sends me and apply it with git, adding author information – as if it were a git-format patch.

I don't really want to start manually rewriting the patch, so I was wondering if there is perhaps a git command I haven't found out about yet that does this.

It seems like a problem others must have had before...

Thanks!
