Also, you should get away from parsing individual characters in
__git_ps1. Characters like + and - are valid in branch names. Coloring
them within the name is not quite intended.

I guess the only way is to produce colors within __git_ps1 (based on an
option). Also, colors would allow to use the same status letters as "git
status -s".
