Subject: [PATCH v3 06/10] t7001: avoid using `cd` outside of subshells

From: Shubham Verma <[email-masked]>
Date: Fri, 12 Feb 2021 01:17:00 +0530

Avoid using `cd` outside of subshells since, if the test fails,
there is no guarantee that the current working directory is the
expected one, which may cause subsequent tests to run in the wrong
directory.

While at it, make some other tests more concise by replacing
simple subshells with `git -C`.
