Actually, the above fails if bash is invoked from a process for which
/proc/$PPID/exename doesn't exist. For example, if I shell out of Windows-based
gvim, $PPID is 1. I found that the following works for this case too.
function setPS1() \
 { PS1="\[\e]0;\w\a\]\[\e[32m\]\u@\h \[\e[33m\]\w\[\e[0m\]\n\$" ; }
if [ -a /proc/$PPID/exename ]; then
 case "$(< /proc/$PPID/exename)" in
 */xterm) function setPS1() {
 PS1="\[033円]0;\w007円033円[32m\]\u@\h \[033円[35m\w033円[0m\]\n$" ;
 } ;;
 esac
