This is good.  Nitpicks below.

Style:
	cat <<-\EOF >expected &&

The \quoting lets reviewers skim through a message without looking
for characters that might be expanded.  The decreased whitespace is
just for consistency.

The --verify here does not accomplish much, since the exit status of
git rev-parse is not propagated to test.  So strictly speaking it
would be more robust to do something like

	head=$(git rev-parse --verify HEAD) &&
	fourth=$(git rev-parse --verify fourth) &&
	test "$head" = "$fourth"

though I do not think it is worth changing.

With or without the following changes,
