diff_opt_parse() is a heavy hammer to just set diff filter. But it's the only way because of the diff_status_letters[] mapping. Add a new API to set diff filter and use it in git-am. diff_opt_parse()'s only remaining call site in revision.c will be gone soon and having it here just because of git-am does not make sense.
