> These 2 tests as well as the previous patches look to me as if they could be refactored (the paradigm is the same: add a certain hook after resetting and then apply the patch, verify that the hook ran/failed)... do you think there is a chance for that?

I had a look, but I think that while it is true that the overall
sequence of each test is the same, the details differ enough that
there's no obvious way to refactor the tests sensibly. For example,
the contents of the hook scripts are not the same, as we need to check
that the hooks are run at the correct stage of git-am execution. And
as such, the verification tests are also different as well.

Junio did correctly point out though that we can shave off 2 lines if
the write_script helper is used (the shebang and the chmod).

Thanks,
Paul
