# Changes the prompt to a Debian-style one that truncates pwd to a max length
# depending on the terminal column width. Also uses the prompt_callback
# function of bash-git-prompt to set the window title to almost the same
# Debian-style. This version has been tweaked for Ubuntu standard terminal 
# fonts.
#
# The prompt will use a Debian-style on the form
#
# relative-path-from-git-toplevel-dir bash-git-prompt-info <exit status>
# HH:MM:SS User@Host ▶
#
# The window title will have the form
# relative-path-from-git-toplevel-dir
#
# Example usage:
# if [ -f ~/.bash-git-prompt/gitprompt.sh ]; then
#   GIT_PROMPT_THEME=Minimal_UserHost
#   source ~/.bash-git-prompt/gitprompt.sh
