[Assist] How to shallow clone from abslibre.git

[bill-auger]

ive never used --single-branch before; but i dont think that is
going to give you a shallow clone - my guess is that will give
you a single branch with its entire history - a shallow clone is
when you are not interested in the history; but only the current
state

you can get a truly shallow clone of any git repo using the
--depth argument, such as:

$ git clone --depth=1 git://git.parabola.nu/abslibre.git
