My takeaways from working with this grammar

[digitcrusher]

This is a pull request of a few fixes I had to apply while adapting this grammar for my text editor. Here's some reasoning behind each commit, from oldest to newest:

1. An example of a color theme which colors these differently is Monokai Pro in Visual Studio Code.
2. This brings parenthesized declarators in line with other declarators (e.g. pointer_declarator).
3. Free stuff. This is yet another case of tree-sitter/tree-sitter#880. It's ugly, but you have to remember that ugly but working code is better than no code at all, if you're writing software for real-world use.
4. Self-explanatory.
