Description:
When 'filetype' option is PKGBUILD in vim (which is set by /usr/share/vim/vimfiles/ftdetect/PKGBUILD.vim included in this package), adjusting indentation of PKGBUILD files by = works incorrectly.
This is because when 'indentexpr' option is empty, vim assumes the file being edited is indented like C-style languages.
This problem can be solved by this package additionally providing indent file for PKGBUILD, together with currently included ftplugin and syntax files.

Since PKGBUILD is basically just a bash script, indent/PKGBUILD.vim should be as easy as
```
if exists("b:did_indent")
finish
endif
let b:did_indent = 1

runtime! indent/sh.vim
```
