Right, this is one fundamental issue; it's always been that way.

It's not 100% clear that if someone running "unset RSP1 RPROMPT" has
really got it in mind that they never want to set a right prompt again,
though, particularly if they're used to how the shell currently works.

It would probably be neatest to make a distinction as an option either
to unset or to the shell (the latter making it easy to provide
compatibility with other shells).

Not new, so can wait for now...
