What does pinning a test mean?

We already have a test that checks the advice that's printed when there 
are conflicts, so could just add

	test_must_fail git show-ref --verify CHERRY_PICK_HEAD

there. Because that test checks the command's output, we know that the 
cherry-pick has failed due to conflicts, and not some other reason. 
Using test_must_fail() here without checking the error message means we 
don't verify the reason that the cherry-pick failed.

Thanks
