Re: [GSOC][PATCH 1/1] t3701: Avoid suppression of exit status of git
Hello, Edwin.
In subject line "t3701: Avoid suppression of exit status of git" -- the first word after a colon shouldn't be capitalized. By the way, similar existing commits call it:
don't lose "git" exit codes
and
preserve "git" exit codes

Bash is not the only Shell used for running Git's test suite, so referring to it like this in the commit message might not be a good idea.
See also similar commit 9fdc79ecba ("tests: don't lose misc "git" exit codes", 2023-02-06) for inspiration in writing the commit message.

Code style here and in all output redirections below: lose the space between redirection and the path, like so:
git show :file >show_file
Also, the suffix "_file" is unnecessary. Just
git show :file >show
or
git show :file >out
or
git show :file >actual
might be better.

Function test_stdout_line_count can be used here instead of "test -z". test_stdout_line_count would produce a more helpful error message in case of test failure.
