One benefit of doing it this way is that future patches will be much
less noisy which convert these callers to also work with any
'repository' object. For instance, after the current patch, we have:

    static void check_connectivity(void)
    {
        struct repository *r = the_repository;
        max = get_max_object_index(r);
        ...

A future patch which converts check_connectivity() to work with any
repository will then require very little change -- just adding an 'r'
argument to the function declaration, and dropping the line which
declares 'r':

    static void check_connectivity(struct repository *r)
    {
        max = get_max_object_index(r);
        ...

So, I'm fine with this patch series' approach of declaring a variable
'r' like this.
