Commit de26f02db1 (t9001, t9116: avoid pipes, 2020-02-14) noticed that
when grepping through the output of a command, there is always a
chance that something could go wrong.
So, redirect the output into a file and grep that file. Thus the log
can be inspected easily if the grep fails.

In test 'test ascending revision range with --show-commit (sha1)',
'out1' variable is used since 'out' variable was already in use.

That "something could go wrong" may deserve little bit more explanation
in the commit message.
One thing when using pipes is that we may loose return codes of programs
being part of the pipe.
The other thing is that it is hard to debug, if the test case fails.
Having the "out" file left on disk allows manual inspection, and tracking
down why it failed.
Having said this, we can make the test case even easier to debug, and consistant
with other test cases, please see below.

That could be written as
grep '^r[0-9]' out | cut -d'|' -f1 >actual &&
test_cmp expected-range-r1-r2-r4 actual
Or something in that style (and similar below).
What do you think ?

Yeah makes sense. I will update the commit message by adding the above
details.

* [PATCH v2] t9116: avoid using pipes

Commit c6f44e1da5 (t9813: avoid using pipes, 2017-01-04) recommends to
avoid using pipes, since the exit code of upstream in the pipe is
ignored. Hence, redirect the output to a file and parse that file.
Commit de26f02db1 (t9001, t9116: avoid pipes, 2020-02-14) noted that
this also allows easy debugging in case the test fails, since the file
will be left on disk and can be manually inspected.

We usually ask for a legal name in a format similar to "<Firstname>
<MaybeMiddleNameInitial> <Lastname>" where <MaybeMiddleNameInitial>
can be omitted. The name should also match what is in the "From:"
field of the emails you send.

It seems that the code that your patch changes is repeated a lot in
this test script. I wonder if it would be better to write a shell
function to avoid those repetitions.

Okay, I will keep that in mind.

Oh yeah, that would be better. I will add a function. Just clarifying,
the function should run the git, grep, cut and test_cmp commands?
Also, could you suggest an appropriate name for this function?
