$ du -sh core-full/.git core-shallow/.git
132M    core-full/.git
18M     core-shallow/.git

Using --depth 5 vs --depth 1 doesn't make much difference:
19M     core-shallow5/.git


Also counting the checkout adds a constant amount:
$ du -sh core-full core-shallow core-shallow5
199M    core-full
84M     core-shallow
85M     core-shallow5


I don't know why your depthed clone was so big.
Could be related to https using the dumb protocol, but still, it's a
difference too big.


So I tried with your parameters:

$ time git clone https://github.com/dantman/mediawiki-core.git a

remote: Counting objects: 398899, done.
remote: Compressing objects: 100% (52956/52956), done.

$ du -sh a b
191M    a
88M     b

$ du -sh a/.git b/.git
122M    a/.git
18M     b/.git


Note that the .git folder in the shallow case is just 18M and I only
needed to download 17M from the net (why were them 48.25M for you?).
For reference, the github clone was at
76dd5fe50aa8f3ed3f436ce737ab339f85e0c63e
and mediawiki/core at 76881580cd9c30681aa65b228e0757c0515bbaa5 (288
commits more) when I performed these tests.
