Subject: [PATCH 3/3] bisect: combine args passed to find_bisection()
Date: Tue, 28 Jul 2020 15:44:16 +0000 [thread overview]
Message-ID: <24d116870e5c9ae03b585737a197f38d679fedb3.1595951056.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.686.git.1595951056.gitgitgadget@gmail.com>
From: Aaron Lipman <alipman88@gmail.com>
Now that find_bisection() accepts multiple boolean arguments, these may
be combined into a single unsigned integer in order to declutter some of
the code in bisect.c
