[GSoC][PATCH v2 0/4] t7401: modernize, cleanup and more

Greetings,

This is the v2 of the previously posted patch series titled 't7401: modernize, cleanup and warn': https://lore.kernel.org/git/20200805174921.16000-1-shouryashukla.oo@gmail.com/

After suggestions from Denton, Taylor and Junio I made some changes:

-> In 2939804509 (t7401: modernize style, 2020-07-23), after suggestions
   from Denton and Taylor, I redirected the output of the two
   'rev-parse' commands to a file and then read from it instead of using
   a pipe '|' operator.

-> Drop the commit ab28283b67 (t7401: ensure uniformity in the
   '--for-status' test, 2020-07-10) and instead combine it with
   00c6289d5e (t7401: change test_i18ncmp syntax for clarity, 2020-07-10).
   This was suggested by Junio and Taylor.

-> Introduce the commit f0b87ddaf6 (t7401: change indentation for
   enhanced readability, 2020-08-11) which improves the indentation of
   the tests in t7401. This was suggested by Junio and Taylor.

-> Remove the WARNING from the commit 0bdb0bd72c (t7401: add a WARNING
   and a NEEDSWORK, 2020-07-23) and instead limit it to a more improved
   NEEDSWORK thus leading to the commit a743c28d71 (t7401: add a
   NEEDSWORK, 2020-07-23). This was suggested by Taylor.

Feedback and reviews are appreciated. I am tagging along a range-diff between the v1 and v2 for ease of review.

Regards, Shourya Shukla

         The tests in 't7401-submodule-summary.sh' were written a long time ago

    +    Using a Git command in the upstream of a pipe might result in us

         While at it, change the word 'test' to 'test script' in the test
