Template is added to new PKGBUILD files twice

[amagura]

Description

When you open a new† PKGBUILD file in vim, PKGBUILD.vim dumps the template into the current buffer twice; this does not, however, happen when you open an empty PKGBUILD file that already exists on the file system.

Interestingly, commenting out the TLoad function in PKGBUILD.vim/plugin/PKGBUILD.vim fixes the issue.

How to reproduce

1. run vim PKGBUILD in a directory without any PKGBUILD files.
   • PKGBUILD.vim should dump the template to the file twice.
2. type ggvGD to empty the file and then type :w.
3. open the file again.
   • This time the template will only be dumped to the buffer once, as expected.

† the file doesn't exist yet and won't exist until vim writes to it for the first time.
