I disagree with this statement. If code isn't prepare to not handle a
`NULL` repository we shouldn't fall back to `the_repository`, but we
should instead prepare the code to handle this case. This of course
requires us to do a ton of refactorings, but that is the idea of this
whole exercise to get rid of `the_repository`.

If a command cannot be converted to stop using `the_repository` right
now we should skip it and revisit once all prerequisites have been
adapted accordingly.
