Better GIT Bash Prompt Formatting than Caroline's

If you set background to white, you might be okay, but, if you prefer the night theme, like I do, you might prefer bold blue :

bolblue="\[\033[01;34m\]"

# Change command prompt
source ~/git-prompt.sh
export GIT_PS1_SHOWDIRTYSTATE=1
# '\u' adds the name of the current user to the prompt
# '\$(__git_ps1)' adds git-related stuff
# '\W' adds the name of the current directory
export PS1="$purple\u$green\$(__git_ps1)$bolblue \W $ $reset"
