Let's try if we can pack a bit more information. For example
Subject: [PATCH] t7601: use "test_path_is_file" etc. instead of "test -f"
would clarify what kind of modernization is done by this patch.

"is currently using" -> "uses".

I am not sure what role "the format" plays in this picture.
test_path_is_file is not new---it has been around for quite a while.

A bit more on this later.

Looking good. If I were writing this, I'll make the whole thing
more like this, though:
t7601: use "test_path_is_file" etc. instead of "test -f"
Some tests in t7601 use "test -f" and "test ! -f" to see if a
path exists or is missing. Use test_path_is_file and
test_path_is_missing helper functions to clarify these tests a
bit better. This especially matters for the "missing" case,
because "test ! -f F" will be happy if "F" exists as a
directory, but the intent of the test is that "F" should not
exist, even as a directory.

The original says "We are happy if c2.c is not a file", so it would
have been happy if by some mistake "git reset" created a directory
there. But the _intent_ of the test is that we do not have anything
at c2.c, and the updated code expresses it better.
