[aur-general] pacman4.1 PKGBUILD-git help needed

I've received a comment this morning from https://aur.archlinux.org/packages/argotlunar-git/

I didn't found an updated PKGBUILD-git.proto nor an example of prepare() for patches. All I had was an example from the VCS_PKGBUILD_Guidelines to convert PKGBUILD to pacman4.1 standards

Alas, makepkg throws an error;

What do I missing? Any advice are welcome!
