I've post the bug near half year. Recently, I got a user require to renew PKGBUILD. But, I think this is bug of AUR script paring problem. As I know AUR's program will not modify. So, the simple method is delete the entry, let me upload again.
If you know the admin of AUR, could you help me to delete the entry of grub4dos. That let me could easy upload a new grub4dos entry. https://bugs.archlinux.org/task/20672
