[PATCH 2/3] git-remote: add -b option to enable tracking remote branches

[Paolo Bonzini <bonzini@gnu.org>]

This commit adds an option to git-remote, providing a way to
switch the default behavior of git-branch from --no-track to
--track.

With `-b` option, local branches created off the remote repository
will be set up to track the remote repository, so that `git pull`
with no parameters does the right thing while you are on your local
branch.
