commands: work around a new flake8 failure

Suddenly, on the new f43 image ci run flake8 fails. Looking at the error
and the code I think this failure is incorrect but I don't want to block
the CI and wait for flake8 to be changed. The workaround is low cost and
not much harder to understand than the original code.
