# 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.
#
# The prompt will use a Debian-style on the form
#
# [user@host: <truncated PWD>] [bash-git-prompt-info]
# HH:MM $
#
# The window title will have the form
# user@host: <truncated PWD>

# Example usage:
# if [ -f ~/.bash-git-prompt/gitprompt.sh ]; then
#   GIT_PROMPT_THEME=TruncatedPwd_WindowTitle_NoExitState
