vim-patch:c0f7505: runtime(lua): add/subtract a 'shiftwidth' after '('/')' in indentexpr

Problem:

- Current lua indentexpr does not indent for '(' ')'.
- Missing indent test for lua.

Solution:

- Match '(', ')' in `function GetLuaIndentIntern`.
- Add an indent test for lua.

closes: vim/vim#15364
