I'd just like to say that I like this. I've never actually used
rprompts but this with the transient_rprompt option (new since 4.0.2)
is useful. For one thing, it makes life easier if I decide to cut 'n'
paste the lines into an editor or other terminal because I don't then
have a prompt to get rid of. I fear that other people may want a
separate transient_rprompt2 option with this.

I'm not sure whether the negative integers part might ever be useful
though I have no objections because it is logical. I'd be tempted to
use negative numbers for reversing the order but -0 not being a
distinct number from +0 makes that less clean as a solution.

Note that these patches do apply to the latest code from cvs. Has
anyone else tried them?
