Subject: [PATCH v3 7/9] rebase -i -x: add exec commands via the rebase--helper
Date: Tue,  5 Dec 2017 12:52:33 -0500	[thread overview]
Message-ID: <20171205175235.32319-8-liambeguin@gmail.com> (raw)
In-Reply-To: <20171205175235.32319-1-liambeguin@gmail.com>

Recent work on `git-rebase--interactive` aims to convert shell code to
C. Even if this is most likely not a big performance enhancement, let's
convert it too since a coming change to abbreviate command names
requires it to be updated.
