This is unnecessary:

The default implementation will automatically run require(MAIN).setup(opts) if opts or config = true is set.

Hmm it's been a bit, but iirc I tried the code in the README and it didn't work, forcing me to modify it to the contents of the PR.

I no longer use this plugin as NeoVim 0.10.0 includes block commenting by default ( https://gpanders.com/blog/whats-new-in-neovim-0.10/#builtin-commenting ), and this PR has been unmerged for 2 months, so I'm not going to spend any time trying to reproduce.

Didn't think it supported nested languages. Nice, thanks for the link!
