Nit: please wrap your commit messages at 72 characters instead of 80.

Makes sense.

Is there a reason that you assign use/assign 'r' here? I can find a few
other such instances of it in:
$ git grep -l 'struct repository \*r = '
builtin/merge-tree.c
builtin/sparse-checkout.c
builtin/update-index.c
fetch-pack.c
read-cache.c
t/helper/test-reach.c
tree.c
but I'm not sure that it's necessary here. Could you instead pass
'the_repository' directly to the functions that now require it?

For example, changing this line to:
max = get_max_object_index(the_repository);

Otherwise this looks pretty good.
