Ah, okay. Is this true for test_expect_code too? It also has a git command
in the example, but it says <command>, not <git-command>:

 - test_expect_code <exit-code> <command>

   Run a command and ensure that it exits with the given exit code.
   For example:

	test_expect_success 'Merge with d/f conflicts' '
		test_expect_code 1 git merge "merge msg" B master
	'

Yes, it's just a matter of taste, but your rewrite is even better.
