They were git repos, right? I am new to git, but my understanding is you pretty much have to type
git clone --i-dont-want-a-full-copy-of-the-repository-please-screw-me-over-if-the-master-vanishes
to be in a position where you are "dependent" on the code (i.e. have looked at it, ever) and do not have a full copy of the entire project extending to the mists of prehistory.
[Edit: apparently the actual command is
git clone --depth (some number)
I like my version better.]
