[GSoC][PATCH] lib-read-tree-m-3way: modernize a test script (style)

[Shaoxuan Yuan <shaoxuan.yuan02@gmail.com>]

As a microproject, I found another small fix regarding styling to do.

I changed the old style '\' (backslash) to new style "'" (single
quotes).

And I also fixed some double quotes misuse.

Other than that, I forgot to introduce myself in the last patch and
here it goes:

I'm Shaoxuan Yuan, currently a sophomore majors in Computer Science and Engineering
(CSE) @ University of California, Irvine. 

I have prior open-source experience in which I was [maintaining|contributing to] the
Casbin community. My main language is Python, and I'm a C newbie
because I'm quite interested in contributing to git (since it is in my main daily
toolkit and it is a charm to wield :-) ).

And for now I'm still taking baby steps trying to crack some test script
styling issues. After getting more familiar with the git contribution
process, I will try something bigger (though not THAT big) to get a
firmer grasp of git.
