[GSoC][PATCH v3 0/3] Avoid using pipes

[Jonathan Chang <ttjtftx@gmail.com>]

Hi,

This is my SoC 2019 Microproject: "Avoid pipes in git related commands
in test scripts".

Changes since v2:
	- drop changes to other 2 files as suggested by Christian Couder[1]
	- rename commit message from "t0000-basic:" to "t0000:"[1]
	- use better commit message suggested by Thomas Gummerer[2]
		and Christian Couder[3]
	- fix the incorrect transformation pointed out by Eric Sunshine[4]
	- rename commit message to "fix indentation" as seen in:
		25e3d28efd ("submodule.c: fix indentation", 2018-11-28)
		d4cddd66d7 ("worktree.c: fix indentation", 2016-01-18)
