I forgot to mention a couple of things.

If you do change that to e.g. "myvimdiff" you'll need the $LOCAL and $REMOTE params as well; probably something like:

[difftool "myvimdiff"]
	cmd = vim -R -d -c wincmd l \"$LOCAL\" \"$REMOTE\"

$ git difftool -y -t myvimdiff

Secondly, git-difftool receives both the pre and post-image and doesn't actually receive the output of git-diff, so passing --patience unfortunately won't do what you're expecting it to do. Piping the output of git-diff to something like kompare(?) is probably the only way to get the nice --patience result.

It'd be nice if all diff/merge tools supported the patience diff algorithm but that's not the case right now.
