Subject: [PATCH v2 11/17] rebase: extract create_autostash()
Date: Tue, 24 Dec 2019 06:05:08 -0500	[thread overview]
Message-ID: <1b5bbe66dc4a6034f465ce565eef4d34f8db8124.1577185374.git.liu.denton@gmail.com> (raw)
In-Reply-To: <cover.1577185374.git.liu.denton@gmail.com>

In a future commit, we will lib-ify this code. In preparation for
this, extract the code into the create_autostash() function so that it
can be cleaned up before it is finally lib-ified.

This patch is best viewed with `--color-moved` and
`--color-moved-ws=allow-indentation-change`.
