Subject: [PATCH 3/3] git-rebase-script: rebase local commits to new upstream head.
Date: Thu, 23 Jun 2005 16:29:09 -0700	[thread overview]
Message-ID: <7v4qboejp6.fsf_-_@assigned-by-dhcp.cox.net> (raw)
In-Reply-To: <7v4qbofym7.fsf_-_@assigned-by-dhcp.cox.net> (Junio C. Hamano's message of "Thu, 23 Jun 2005 16:21:36 -0700")

Using git-cherry, forward port local commits missing from the
new upstream head.  This depends on "-m" flag support in
git-commit-script.
