} I tried it without any highlighting.

It works for me in xterm if I e.g. assign PS1="$PS1%U" ... in fact for
the most part even the active region highlight doesn't screw it up, you
appear to be doing a good job of turning off only the seuqnces that you
previously turned on.  (I did not try more complicated effects than %U.)

(It's a bit odd that %U persists into the right prompt unless turned off
with PRS1="%u$RPS1" but it has always been that way.)

Sounds reasonable to me, but could get ugly if a widget were to change
it on the fly -- do you trap that and reprint the entire buffer, or do
you allow blotches of different attributes as areas are selectively
repainted, or do you make that setting read-only in widgets?
