Code review comment for ~racb/git-ubuntu:reimport-service

Very nice! And thanks for the range diff, I always forget to do that but it's quite helpful.

I did spot a couple typos, feel free to fix up when landing, no re-review needed:

* "These numbers are hardcoded becuase they must match the what we use"
  - sp. "becuase"
  - del 'the'
