Can I ask why you're sending this PR? These mistakes seem harmless, the PR is also harmless, but it costs time for the maintainer to validate that it's not changing behavior, so I wonder if it's worth creating such PRs in future for projects that you are not already contributing to.

For example (and I know this might sound petty but it's the sad reality of my mindset) I am "only" the maintainer of the Bazel integration in this repository, so I need to decide whether this is likely to be outside my territory, or whether I would just annoy the primary maintainer by assigning it to them.

@drigz Ok will not reopen similar PRs again. Feel free to close the PR - or I can close it...

NP, I think this is a net improvement so I suspect it's best to merge. Sorry if I came across as standoffish, and I hope this doesn't put you off making bug fixes or other contributions in future!
