MAINT: More scoped `nolint` rules

[HaoZeke]

this is really overly pedantic, but you could consider specifying which rule to ignore in the #nolint comments instead of ignoring every rule (it is considered generally a best practice, but does not have real impact here). This is not needed if you would need to ignore several rules

First noted here: ropensci/software-review#606 (comment).

For C++ functions I'm not sure this makes any sense...
