From: Thomas Rast Date: Sat, 22 Feb 2014 09:17:51 GMT Subject: [PATCH v2 3/8] merge-recursive: -Xindex-only to leave worktree unchanged Message-ID: <2e56b258bca6cf83c322da4be85c42c7b54f6a3e.1393059605.git.tr@thomasrast.ch> In-Reply-To: From: Thomas Rast Using the new no_worktree flag from the previous commit, we can teach merge-recursive to leave the worktree untouched. Expose this with a new strategy option so that scripts can use it.
