I agree (with Eli).  I don't see a bug here, and everything
suggested so far does not sound like an improvement.

FWIW, if we are envisaging changing the prompt implementation
then I think the prompt should be more amenable to Lisp (not
done in C), and that any prompt features (including text
properties, including `face' and read-only) should be default
behavior only.  At least a start would be to allow code to
provide a propertized prompt (esp. wrt `face') and have that
be used/respected and not overwridden.
