Shell script to override Git Bash's bash prompt on Windows (Git 2.0+)

git-prompt.sh

# Create at $HOME/.config/git/git-prompt.sh

# The same content as the '%ProgramFiles%\Git\etc\profile.d\git-prompt.sh'
# file, but with the parts I don't like commented out.

# Many thanks to the great overview here:
# https://alanbarber.com/2015/12/30/how-to-customize-the-git-for-windows-bash-shell-prompt/
# and the original file for making it easy enough to see how to override 
# the existing settings.
