This clones only the main branch (master). Since this is where almost
all Emacs history is located it won't make much difference size wise.

Git does not have any concept like Bazaar's lightweight checkouts -
nor does any other dvcd afaik. Depth 1 truncates all history except
for the most recent commit. From `man git clone`:

A shallow repository has a number of limitations (you cannot clone or
fetch from it, nor push from nor into it), but is adequate if you are
only interested in the recent history of a large project with a long
history, and would want to send in fixes as patches.
