```
The test_path_is* functions provide debug-friendly messages upon failure.

The body looks fine to me. Your subject is getting a little long,
however. Typical guidance would be somewhere around 50 (at least in my
opinion, I thought we had something in Documentation/CodingGuidelines,
but I couldn't find anything).

Maybe something instead like:

  t0000: replace 'test -f' with helpers

or:

  t0000: modernize test style

If you're looking for inspiration, you can use `git log`'s `-S` flag to
look for anything that mentions 'test_path_is_file' to see how similar
patches have been written in the past. (When I was recommending
alternatives, I ran "git log --oneline -Stest_path_is_file -- t").

I think that you meant to put this "Outrachy ..." _below_ the
triple-dash line. Incidentally, Git still applies this patch just fine,
but it is easier for reviewers to pick it up if the "---" line is left
alone.

This looks totally correct to me.

Thanks,

Thanks for a great educational input.

By nature of "microproject" exchange, it is almost trivial to get
the patch text right after an exchange.  The problems are typically
so easy that there is only one way to write the code part correctly.

Polishing proposed log message is much harder ;-)

Thanks.
