tramp (2.0.52); Tramp stalls when parsing prompt with Escape sequences |

Tramp hangs (and eventually times out) when connecting to one of our
machines. It looks like it cannot parse the shell prompt. My settings
seem reasonable - I'm not sure if PS1 should be set to something else
depending on the terminal used to log in.
# set prompt: address@hidden:/directory $ ''
export PS1="address@hidden:\W] "
case `id -u` in
0) export PS1="${PS1}#";;
*) export PS1="${PS1}";;
esac
export PS1="\e[30;47m ${PS1}\e[0m "
Users can set their prompts to whatever they wish. So is its form
documented so that tools like Tramp can safely rely on it?
