I set my prompt without using it, with something approximating this
being defined in my .bash_profile. I think the use of ' instead of " 
causes evaluation of __prompt_githead be delayed until the prompt is 
displayed.


  PS1='$(__prompt_githead) '$PS1

  __prompt_githead() {
  PS_GIT=$(git-symbolic-ref HEAD 2>/dev/null) || exit
  echo -n " $(basename $PS_GIT)" 
  }
