Subject: [PATCH v6 7/9] sequencer: reencode old merge-commit message
Date: Mon, 11 Nov 2019 13:03:40 +0700	[thread overview]
Message-ID: <4dfdd4b83ed0cf59ae1a4e888ba1f7e4c7d1f80f.1573452046.git.congdanhqx@gmail.com> (raw)
In-Reply-To: <cover.1573452046.git.congdanhqx@gmail.com>

During rebasing, old merge's message (encoded in old encoding)
will be used as message for new merge commit (created by rebase).

In case of the value of i18n.commitencoding has been changed after the
old merge time. We will receive an unusable message for this new merge.

Correct it.

This change also notice a breakage with git-rebase label system.
