ksh starting as root will refuse to import a PS1 prompt unless it
contains a '#' character. Make it also accept the \$ PS1 sequence
(which is supposed to automagically be $ or # depending on the user
running the shell) unless ksh has been started in sh-compatibility
mode.
pointed out by millert@ when I asked why my SUDO_PS1 was not being
honoured; ok millert@
