the git branch. I couldn't live without it now. One other thing you might be
interested in is bash completion, it is very well developed for Git and even
completes on custom aliases. Installation depends on your distro, but typing
git <tab><tab> would give all common completions, and even options will be
expanded/completed.

We should possibly add something to the wiki for those wishing to use some
of the extras available such as custom prompts and bash completion.

Thanks,
