Fix up colored git-prompt

The main point is to match the colors to be more close to the color
output of "git status -sb".

 - the branchname is green, or in red when the HEAD is detached;

 - the flags are either red or green for unstaged/staged and the
   remaining flags get a different color or none at all.
