Subject: [PATCH 03/26] bisect--helper: `decide_next()` helper function.
Date: Sun, 24 Feb 2019 02:11:17 -0800 (PST)	[thread overview]
Message-ID: <cadc46442d5c960caa58227092289fa2f44fb96f.1551003074.git.gitgitgadget@gmail.com> (raw)
In-Reply-To: <pull.117.git.gitgitgadget@gmail.com>

From: Tanushree Tumane <tanushreetumane@gmail.com>

introduce `decide_next()` helper function from `bisect_next_check()`
for better and clear understanding.

convert `*...warning` char pointers to `...warning[]`char arrays, as
char [] only creates char array while char * creates both char array
and a pointer to that char array.
