This does not exactly look like a "refactoring". There are at least
two differences and it is the courteous thing to do to readers to
note them and explain why these differences do not impact the
correctness of the tests, I would say.
* The original uses a dedicated branch, while the rewritten uses a
dedicated repository for these tests. This does not impact the
correctness as long as all the tests that originally used the
branch are made to run in this new repository with "git -C".
* The youngest change removes the binary sample file, while the
rewritten only truncates it. This does not impact the
correctness, because a removed file and a file whose lines are
all removed behave in the same way with respect to -G/-S. Both
will reduce the number of occurrence of -S<needle>, and make
"removal" (-) lines of -G<needle> appear in the patch.

The --append on the first one does not make any difference ;-)

The original removes the file at the end, while this merely
truncates it.
