From 4a5b63e3e966184aa1ff32770410d485202562ca Mon Sep 17 00:00:00 2001
From: Junio C Hamano <junkio@cox.net>
Date: Sun, 11 Sep 2005 11:35:20 -0700
Subject: [PATCH] [PATCH] Omit patches that have already been merged from
 format-patch output.

This switches the logic to pick which commits to include in the output
from git-rev-list to git-cherry; as a side effect, 'format-patch ^up mine'
would stop working although up..mine would continue to work.
