Check out a remote branch in git
If you would like to checkout the branch groups, you can simply say this in recent versions of Git:
git fetch origin
git checkout groups
This will automatically track origin/groups from a local branch groups.
In older Git versions you need to say this:
git fetch origin
git checkout --track origin/groups

git "fatal: bad config file line" after checking out branch
If git gives you an error message such as "fatal: bad config file line 123 in .git/config" after you tried to checkout a branch with a very long branch name, you very likely come across a bug in git version < 1.8.
