- Ignore comments when aligning arguments, parameters and fields.
- Apply simpler rules to simpler usage of anonymous functions.
- Better handling of table as a function argument.
(lua-ts--comment-first-sibling-matcher):
(lua-ts--first-real-sibling-anchor):
(lua-ts--last-arg-function-call-matcher):
(lua-ts--top-level-function-call-matcher): New function.
(lua-ts--g-parent):
(lua-ts--g-g-parent): New function.
(lua-ts--g-g-g-parent): Use it.
* test/lisp/progmodes/lua-ts-mode-resources/indent.erts:
