[PATCH 03/26] bisect--helper: `decide_next()` helper function.

["Tanushree Tumane via GitGitGadget" <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.
