That's of course totaly right and what I've meant, but unfortunately not what I've written ;-)

Hmm, if I get you right you _partly_ agree with me in choosing "pick" for am --rebasing... But cherry-pick should only be chosen if a simple git-apply failed first. Right?

I just got another idea which could easily be done and perhaps is the
right thing :)
Generating
	patch -C <commit> -3 <file>

This takes authorship and message from <commit> and does the usual threeway-fallback behavior.

What do you think?

That's right, but that would require me to hack around in git-rebase which I tried to avoid for now. :)
