Subject: [PATCH 29/29] bisect--helper: reimplement `bisect_run` shell function in C
Date: Mon, 20 Jan 2020 15:38:00 +0100 [thread overview]
Message-ID: <20200120143800.900-30-mirucam@gmail.com> (raw)
In-Reply-To: <20200120143800.900-1-mirucam@gmail.com>
From: Tanushree Tumane <tanushreetumane@gmail.com>
Reimplement the `bisect_run()` shell function
in C and also add `--bisect-run` subcommand to
`git bisect--helper` to call it from git-bisect.sh.
