In my opinion, we should first think about how we handle the situation
where we run builtins outside of the repository. The most easiest way is
to pass the fallback object (aka "the_repository").

However, this seems a little strange. We are truly outside of the
repository but we really rely on the "struct repository *" to do many
operations. It's unrealistic to change so many interfaces which use the
"struct repository *". So, we should just use the fallback idea at
current.

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.
