Overall, I'm a bit hesitant towards changing actual code under the umbrella of "fixing typos".

I am hesitant too, although I am sympathetic to fixing where it is not problematic. I don't really have cycles to dig in hard right now.

@kianmeng Could you amend (or new, whatever) to just files for human reading? That seems mergeable much more easily and we'll get half done, arguably the more important half.

@gdt Noted. I've reverted changes to the source code and keep only those in comments and documentation. Let me know if I miss out anything.

Looks good to me, but would appreciate someone else reviewing too.

I approved running the CI workflow; obviously that has to pass but I am pretty sure it will.

@kianmeng Thanks for contributing.
