The changes in `unpack_trees()` are a bit misleading -- while it reads as if we don't use `the_repository` anymore, we still do because the function starts with:

  int unpack_trees(unsigned len, struct tree_desc *t, struct unpack_trees_options *o)
  {
  	struct repository *repo = the_repository;

So would it make sense to maybe have a separate patch where we inject a repository as a parameter to `unpack_trees()`?

Once that's done we only have a handful of other places, and in all but two cases we have a repository available via the index. Do we maybe want to go all the way so that we can drop `USE_THE_REPOSITORY_VARIABLE` at the end of this series?

Thanks!
