PS1 prompt with git branch

ps1_git.sh

# Idea from:
#
# https://bbs.archlinux.org/viewtopic.php?pid=1068202
# Colors https://wiki.archlinux.org/index.php/Color_Bash_Prompt

# Note: We require escape '\[' and '\]' around the ansi escapes
# (i.e. '\e[0m')! Otherwise the shell does not know that the ansi
# escapes should be excluded from the line wrapping calculation.
#
# See
