- We are seeing flaky documentation lint checks that do not always catch
  when a file inside the documentation is set with the executable bit.
  The check to find executable documents runs inside a subshell and its
  error output is not being redirected, nor would it count those errors
  when running `wc -l`. It seems implausible that we are failing to `cd`
  into the correct directory, but this is the one method I know of that
  would cause the `find` expression to fail silently in the logs. It is
  also just useful to see that yes, we are running the documentation
  linter against a reasonable directory in the logs.
