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

I've received a comment this morning from https://aur.archlinux.org/packages/argotlunar-git/ gtmanfred wrote: 'https://wiki.archlinux.org/index.php/VCS_PKGBUILD_Guidelines pacman 4.1 supporst git also, patches should be in the prepare() function' 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; ==> Retrieving sources... ==> ERROR: /src/argotlunar-git/argotlunar is not a clone of git:// github.com/mourednik/argotlunar Aborting... http://sprunge.us/LNCi What do I missing? Any advice are welcome!
