Hmm, on second thought, that page is wrong.  You need to enclose
non-printing sequences in \[ \] pairs so that bash can calculate how
wide your prompt is.  It will be subtly screwy if you don't enclose
each ANSI sequence in \[ \].

I do it like this:

# color defs
PLAIN="\[\e[00m\]"
GREEN="\[\e[32m\]"
YELLOW="\[\e[33m\]"
BLUE="\[\e[34m\]"
BRIGHTBLUE="\[\e[01;34m\]"
# etc...

case "$TERM" in
xterm-color|xterm|cygwin)
    PS1="${GREEN}\u${YELLOW}@${GREEN}\h${PLAIN}:${BRIGHTBLUE}\w${PLAIN}$ "
    ;;
*)
    PS1="\u@\h:\w$ "
   ;;
esac
