While you're there, you may want to get rid of this hardcoded 41 and
write GIT_SHA1_HEXSZ + 1 instead.

Please write all code within test_expect_success including this
(t/README:

 - Put all code inside test_expect_success and other assertions.

   Even code that isn't a test per se, but merely some setup code
   should be inside a test assertion.
