Thanks for reporting that a single test is failing.

Not sure what you mean by currently accumulated commits and making a
new version.
This does not merit a new version. If you've created local commits and
want to delete them
so you can make a new version yourself, you can either clone again to
start from scratch
or discard e.g., the topmost commit along with any uncommitted changes
by running this:

  git reset --hard HEAD^

The issue you found is due to a problem solely with the test, not with
how diff works.
The attached fix makes it so this small test now also passes, even
with newer GNU make.
