[jurre]

Looks good to me, thanks for fixing this! Should we add a test that covers the scenario?

[deivid-rodriguez]

@jurre I considered that but since an existing test already caught the issue, I decided to change that test to check for the correct result and don't add any new tests. Do you think it's fine?

I pushed an extra tweak to reuse git commit checkers since I noticed dry-run.rb was showing a lot of duplicated requests with the previous implementation.
