thanks for reporting. I'm assuming that the LESSOPEN env var is non-empty in the Void Linux CI runner? Probably it makes sense for the integration tests to clear the LESSOPEN env var (except for the tests which already set it), as they likely assume it is blank except for those tests.

Hm, I assumed it was a simple issue with those help output tests being hardcoded for the default-features case, where clap generates the --lessopen flag help conditionally.

Oh that would make more sense, somehow I didn't really understand the diff so skipped over that possibility. Thanks for reporting, it makes sense to get that fixed.
