c. Still clone from the remote, but set up alternates to a single
local "reference repository". Then all common objects will be stored
only once in this reference repository. The advantage to (a) is that
your remotes are actually set up sensibly.

(Note that the blog post talks about .git + checkout sizes, in case
someone got confused like I did, counting only .git. :-)
