I understand the motivation, but I suspect skipping mailsplit
might be simpler, like this untested code perhaps?

	case "$one" in
        '')
        	... original code ...
		;;
        *)
		one=`printf "%${prec}d" 1`
        	cat "$@" >"$dotest/$one"
                echo "$one" >"$dotest/last"
                ;;
	esac
