Yes, the hook was written exactly for validation, to preempt an
undesirable commit from being created.

We might want to do two things:

(1) clarify the documentation to say that the hook should not try
    mutation, and

(2) detect and error out when the hook does try to make any
    mutation.

I am not sure if (2) is feasible, though.

Thanks.
