Subject: [GSoC][PATCH v2 3/6] rebase -i: support --committer-date-is-author-date
Date: Tue, 13 Aug 2019 01:12:57 +0530 [thread overview]
Message-ID: <20190812194301.5655-4-rohit.ashiwal265@gmail.com> (raw)
In-Reply-To: <20190812194301.5655-1-rohit.ashiwal265@gmail.com>
rebase am already has this flag to "lie" about the committer date
by changing it to the author date. Let's add the same for
interactive machinery.
