From: David Soria Parra <dsp@xxxxxxx>
Add a --track option that can be used to clone just the
given branch from the remote and nothing else. This is done
by setting the remote.<branch>.fetch option before cloning.
This option cannot be used together with --mirror.
For example using
git clone --track next git://git.kernel.org/pub/scm/git/git.git
will just clone the next branch from the git.git repository.
The option is called --track to ensure clean wording with
'git remote add --track'.
