Basically every git repository needs to be entirely self-sufficient,
that is, it should be possible to check out a copy without referring
to any external repositories.  So your initial push to an empty
repository will always upload all the objects, even if you pulled from
some other.

The good news is that if your friends who checked out of the main
repository want to try out your branch, it *won't* accidentally
download all the extra objects over again.  git will notice that they
already have the same objects (retrieved from the main repo) and
download only the new ones.

So yes, some space is "wasted" on your extra repo, but disk space is
cheap anyway (and you now have a backup of the main repo for free :))

Have fun,
