Current git branch in your bash prompt

gistfile1.md

Show the time, the current folder where you are working and the current branch if working on a git repository. Output looks like 19:41:40 Documents@master$ . If using an xterm-256 terminal emulator, hour should be green, cwd white and the branch red.
