I think we could do it if we put the loop inside a subshell that was 
inside test_expect_success(). That would mean we'd have a single test 
for all the various combinations. That script could certainly use more 
cleanup to stop running git outside of test_expect_success() and use 
things like test_must_fail(), write_script(), test_commit_message() etc. 
but I think that can always come later. The first patch here is a 
welcome improvement even if it does not fix all the issues in that test 
file. The second patch looks good too.

Thanks for re-submitting these

Phillip
