[PATCH 3/9] bisect: do not use update-ref for BISECT_HEAD

From: David Turner <dturner@twopensource.com>
Date: Jul 24, 2015, 04:45 UTC
Message-ID: <1437713129-19373-4-git-send-email-dturner@twopensource.com>
In-Reply-To: <1437713129-19373-1-git-send-email-dturner@twopensource.com>

Because BISECT_HEAD is a pseudoref, we shouldn't use update-ref to update it. Instead, we simply write to and delete the file.
