OK, so this is the patch that applies the Coccinelle script from the
previous step.

This all makes sense, but I wonder if we should be more careful than
blindly replacing these functions with the same set of arguments
following a new

    get_main_ref_store(the_repository)

For instance, in this hunk, we have a 'struct repository *' in scope via
the 'r' parameter in add-interactive.c::get_modified_files().

I don't think it's wrong per-se to use the_repository here, but it does
create something to clean up in the future.

I haven't looked at other spots throughout this patch, just noticed
this in the first hunk and thought that I'd say something about it.
Otherwise the transformation seems obviously correct.

Thanks,
Taylor
