That may be an appropriate solution and it would avoid adding another hook. And it would solve the issue of "\n" in filenames. The only downside is that you would need to store state in an external file (maybe in GIT_DIR) so that successive calls of the hook script can pick up where the previous invocation ended. It all comes down to ergonomics at this point. I don't mind either solutions as long as validating whole series is possible before sending emails.
