Subject: [PATCH v2 3/4] rebase: teach `reset_head()` to optionally skip the worktree
Date: Fri, 18 Jan 2019 07:09:26 -0800 (PST) [thread overview]
Message-ID: <387071dcd77fde6ceef1daea623b4ae2e0e08166.1547824162.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.24.v2.git.gitgitgadget@gmail.com>
From: Johannes Schindelin <johannes.schindelin@gmx.de>
This is what the legacy (scripted) rebase does in
`move_to_original_branch`, and we will need this functionality in the
next commit.
